Many of the aspects of ctwm’s user interface are controlled by variables
  that may be set in the user’s startup file. Some of the options are
  enabled or disabled simply by the presence of a particular keyword. Other
  options require keywords, numbers, strings, or lists of all of these.
Lists are surrounded by braces and are usually separated by
    whitespace or a newline. For example:
AutoRaise { "emacs" "XTerm" "Xmh" }
 
or
AutoRaise
{
    "emacs"
    "XTerm"
    "Xmh"
}
 
When a variable containing a list of strings representing windows
    is searched (e.g. to determine whether or not to enable autoraise as shown
    above), a string must be an exact, case-sensitive match to the
    window’s name (given by various window properties, such as WM_NAME),
    resource name or class name (both given by the WM_CLASS window property).
    The preceding example would enable autoraise on windows named
    “emacs” as well as any xterm (since they are of class
    “XTerm”) or xmh windows (which are of class
    “Xmh”).
String arguments that are interpreted as filenames (see the
    Pixmaps, Cursors, and IconDirectory below) will prepend the user’s
    directory (specified by the HOME environment variable) if the first
    character is a tilde (~). If, instead, the first character is a colon (:),
    the name is assumed to refer to one of the internal bitmaps that are used to
    create the default titlebars symbols: :xlogo or :iconify (both refer to the
    X used for the iconify button), :resize (the nested squares used by the
    resize button), and :question (the question mark used for non-existent
    bitmap files).
The following variables may be specified at the top of a ctwm
    startup file. Lists of window name prefix strings are indicated by win-list.
    Optional arguments are shown in square brackets:
AlwaysOnTop { win-list }
This variable specifies a list of windows (all windows if
  the list is defaulted) that ctwm will try its best to maintain on top of
  others. This doesn’t work in all case.
AlwaysShowWindowWhenMovingFromWorkspaceManager
When ReallyMoveInWorkspaceManager is present and the user
  is moving a window from the WorkSpaceMap, ctwm display the actual window only
  if it crosses the current active workspace. If
  AlwaysShowWindowWhenMovingFromWorkspaceManager is present, the actual window
  is always visible during the move, regardless of whether it crosses the
  current workspace or not. The Shift key toggles this behaviour.
AlwaysSqueezeToGravity [{ win-list }]
This variable indicates that ctwm should obey window
  gravity when squeezing a window even when the window has a titlebar. Normally,
  ctwm will always squeeze a window that has a titlebar toward the north. The
  optional win-list may be used to control which windows this applies on.
AnimationSpeed speed
The speed argument is a non-negative integer. It
  determines the number of times a second animations (if any) are updated. If
  speed is 0, animations are freezed. The default value is 0.
AutoFocusToTransients
Transient windows get focus automatically when created.
  Useful with programs that have keyboard shortcuts that pop up windows.
AutoLower [{ win-list }]
This variable specifies a list of windows (all windows if
  the list is defaulted) to be automatically lowered whenever the pointer leaves
  a window. This action can be interactively enabled or disabled on individual
  windows using the function f.autolower.
AutoOccupy
This variable specifies that clients will automatically
  change their occupation when their name or icon name changes. The new
  occupation will be recalculated from the Occupy and OccupyAll fields in the
  .ctwmrc file.
AutoPopup [{ win-list }]
This variables specifies a list of windows which will be
  deiconified whenever their name changes. Can be used for xconsole, for
  instance,which adds a "*" to its name whenever something gets
  displayed on the console, or for various mail readers who change their icons
  depending on the presence of unread mail.
First appeared in 4.0.0.
AutoPriority
This variable specifies that ctwm should automatically
  recompute the priority of a window (and its associated icon) when its name
  changes. See also OnTopPriority.
First appeared in 4.0.0.
AutoRaise [{ win-list }]
This variable specifies a list of windows (all windows if
  the list is defaulted) to be automatically raised whenever the pointer has
  come to rest in a window for the amount of time specified by the RaiseDelay
  variable. This action can be interactively enabled or disabled on individual
  windows using the function f.autoraise.
AutoRaiseIcons
Icons are raised when the cursor enters it. Useful with
  ShrinkIconTitles.
AutoRelativeResize
This variable indicates that dragging out a window size
  (either when initially sizing the window with pointer Button2 or when resizing
  it) should not wait until the pointer has crossed the window edges. Instead,
  moving the pointer automatically causes the nearest edge or edges to move by
  the same amount. This allows the resizing of windows that extend off the edge
  of the screen. If the pointer is in the center of the window, or if the resize
  is begun by pressing a titlebutton, ctwm will still wait for the pointer to
  cross a window edge (to prevent accidents). This option is particularly useful
  for people who like the press-drag-release method of sweeping out window
  sizes.
AutoSqueeze { win-list }
These windows will be auto-squeezed (see f.squeeze). i.e.
  automatically unsqueezed when they get focus, and squeezed when they loose it.
  Useful for the workspace manager. Not authorized for icon managers.
BackingStore
Enable usage of backing store on menus and workspace map
  windows. See also NoBackingStore. Added in 4.0.0; in previous versions this
  was the default.
BeNiceToColormap
By defaults new colors are allocated for shadows when a
  3D look is used, but when you specify BeNiceToColormap ctwm uses stipling
  instead of new colors, the effect is less beautiful, but acceptable. In this
  case ClearShadowContrast and DarkShadowContrast have no effects.
BorderBottom pixels
This variable specifies the width in pixels of a
  forbidden zone at the bottom of the screen. All constrained window functions
  (f.movepack, f.move with DontMoveOff, etc...) will consider this zone as
  offscreen. Default is 0.
BorderColor string [{ wincolorlist }]
This variable specifies the default color of the border
  to be placed around all non-iconified windows, and may only be given within a
  Color or Monochrome list. The optional wincolorlist specifies a list of window
  and color name pairs for specifying particular border colors for different
  types of windows. For example:
BorderColor "gray50"
{
    "XTerm" "red"
    "xmh"   "green"
}
 
The default is “black”.
BorderLeft pixels
This variable specifies the width in pixels of a
  forbidden zone at the left of the screen. All constrained window functions
  (f.movepack, f.move with DontMoveOff, etc...) will consider this zone as
  offscreen. Default is 0.
BorderResizeCursors
This variable specifies that ctwm should use resizing
  cursors when the pointer is on the window border. To be used preferably when
  you have bound a button to f.resize in the frame context.
BorderRight pixels
This variable specifies the width in pixels of a
  forbidden zone at the right of the screen. All constrained window functions
  (f.movepack, f.move with DontMoveOff, etc...) will consider this zone as
  offscreen. Default is 0.
BorderShadowDepth pixels
This variable specifies the depth of the shadow ctwm uses
  for 3D window borders, when UseThreeDBorders is selected.
BorderTileBackground string [{ wincolorlist }]
This variable specifies the default background color in
  the gray pattern used in unhighlighted borders (only if NoHighlight
  hasn’t been set), and may only be given within a Color or Monochrome
  list. The optional wincolorlist allows per-window colors to be specified. The
  default is “white”.
BorderTileForeground string [{ wincolorlist }]
This variable specifies the default foreground color in
  the gray pattern used in unhighlighted borders (only if NoHighlight
  hasn’t been set), and may only be given within a Color or Monochrome
  list. The optional wincolorlist allows per-window colors to be specified. The
  default is “black”.
BorderTop pixels
This variable specifies the width in pixels of a
  forbidden zone at the top of the screen. All constrained window functions
  (f.movepack, f.move with DontMoveOff, etc...) will consider this zone as
  offscreen. Default is 0.
BorderWidth pixels
This variable specifies the width in pixels of the border
  surrounding all client window frames if ClientBorderWidth has not been
  specified. This value is also used to set the border size of windows created
  by ctwm (such as the icon manager). The default is 2.
ButtonIndent pixels
This variable specifies the amount by which titlebuttons
  should be indented on all sides. Positive values cause the buttons to be
  smaller than the window text and highlight area so that they stand out.
  Setting this and the TitleButtonBorderWidth variables to 0 makes titlebuttons
  be as tall and wide as possible. The default is 1 if UseThreeDTitles is not
  set, 0 if it is set.
CenterFeedbackWindow
The moving and resizing information window is centered in
  the middle of the screen instead of the top left corner.
ClearShadowContrast contrast
Indicates to ctwm how to calculate the clear shadow color
  for 3D items. The value is a comprised between 0 and 100. The formula used is
  :
    clear.{RGB} = (65535 - color.{RGB}) * (contrast / 100).
 
Has no effect if BeNiceToColormap is active.
ClickToFocus
Focus windows by clicking on them, rather than merely
  mousing over them.
ClientBorderWidth
This variable indicates that border width of a
  window’s frame should be set to the initial border width of the window,
  rather than to the value of BorderWidth. If Use3DBorders is set this variable
  is automatically unset.
Color { colors-list }
This variable specifies a list of color assignments to be
  made if the default display is capable of displaying more than simple black
  and white. The colors-list is made up of the following color variables and
  their values: DefaultBackground, DefaultForeground, MenuBackground,
  MenuForeground, MenuTitleBackground, MenuTitleForeground, and MenuShadowColor.
  The following color variables may also be given a list of window and color
  name pairs to allow per-window colors to be specified (see BorderColor for
  details): BorderColor, IconManagerHighlight, BorderTileBackground,
  BorderTileForeground, TitleBackground, TitleForeground, IconBackground,
  IconForeground, IconBorderColor, IconManagerBackground, and
  IconManagerForeground. For example:
Color
{
    MenuBackground      "gray50"
    MenuForeground      "blue"
    BorderColor         "red"    { "XTerm" "yellow" }
    TitleForeground     "yellow"
    TitleBackground     "blue"
}
 
All of these color variables may also be specified for the
    Monochrome variable, allowing the same initialization file to be used on
    both color and monochrome displays.
ConstrainedMoveTime milliseconds
This variable specifies the length of time between button
  clicks needed to begin a constrained move operation. Double clicking within
  this amount of time when invoking f.move or other similar moving functions
  will cause the window only be moved in a horizontal or vertical direction.
  Setting this value to 0 will disable constrained moves. The default is 400
  milliseconds.
Note that this also affects double clicking in f.raiseorsqueeze,
    and potentially other places that need to track double clicks. It should
    probably be renamed.
Cursors { cursor-list }
This variable specifies the glyphs that ctwm should use
  for various pointer cursors. Each cursor may be defined either from the cursor
  font or from two bitmap files. Shapes from the cursor font may be specified
  directly as:
where cursorname is one of the cursor names listed below, and
    string is the name of a glyph as found in the file <X11/cursorfont.h>
    (without the “XC_” prefix). If the cursor is to be defined
    from bitmap files, the following syntax is used instead:
    cursorname "image" "mask"
 
The image and mask strings specify the names of files containing
    the glyph image and mask in bitmap(1) form. The bitmap files are located in
    the same manner as icon bitmap files. The following example shows the
    default cursor definitions:
Cursors
{
    Frame       "top_left_arrow"
    Title       "top_left_arrow"
    Icon        "top_left_arrow"
    IconMgr     "top_left_arrow"
    Move        "fleur"
    Resize      "fleur"
    Menu        "sb_left_arrow"
    Button      "hand2"
    Wait        "watch"
    Select      "dot"
    Destroy     "pirate"
}
 
DarkShadowContrast contrast
Indicates to ctwm how to calculate the dark shadow color
  for 3D items. The value is a comprised between 0 and 100. The formula used is
  :
    dark.{RGB}  = color.{RGB} * ((100 - contrast) / 100),
 
Has no effect if BeNiceToColormap is active.
DecorateTransients
This variable indicates that transient windows (those
  containing a WM_TRANSIENT_FOR property) should have titlebars. As of 4.0.0
  this is the default.
DefaultBackground string
This variable specifies the background color to be used
  for sizing and information windows. The default is
  “white”.
DefaultForeground string
This variable specifies the foreground color to be used
  for sizing and information windows. The default is
  “black”.
DontIconifyByUnmapping { win-list }
This variable specifies a list of windows that should not
  be iconified by simply unmapping the window (as would be the case if
  IconifyByUnmapping had been set). This is frequently used to force some
  windows to be treated as icons while other windows are handled by the icon
  manager.
DontMoveOff
This variable indicates that windows should not be
  allowed to be moved off the screen. It can be overridden by the f.forcemove
  function.
DontNameDecorations
Disable setting WM_NAME properties on the various
  decoration windows ctwm puts around the windows it manages. These are handy to
  keep track of what’s what when poking through the list of windows on
  the screen, but can confuse some tools that don’t expect to find them
  there (xwit is known to be one of them). First appeared in 4.0.2.
DontPaintRootWindow
This variable tells ctwm not to paint the root window,
  whatever you told in the Workspaces specification. This is useful to have
  pixmaps in the Workspace Map but not on the root window.
DontSave { win-list }
These windows won’t have their characteristics
  saved for the session manager.
DontSetInactive { win-list }
These windows won’t be set to InactiveState when
  they become invisible due to a change workspace. This has been added because
  some ill-behaved clients (Frame5) don’t like this.
DontShowWelcomeWindow
Indicates the same as the -W option: the welcome window
  is not shown.
DontSqueezeTitle [{ win-list }]
This variable indicates that titlebars should not be
  squeezed to their minimum size as described under SqueezeTitle below. If the
  optional window list is supplied, only those windows will be prevented from
  being squeezed.
DontToggleWorkSpaceManagerState
Turns off the feature toggling the workspace manager
  state to/from map/button state when you press ctrl and the workspace manager
  window is in focus.
DontWarpCursorInWMap
Tells ctwm not to warp the cursor to the corresponding
  actual window when you click in a small window in the workspace map.
EWMHIgnore { message-types }
Sets EWMH message types that ctwm will ignore. This is
  only valid if built with USE_EWMH (currently on by default). The following
  example shows all the valid options:
EWMHIgnore
{
    # Window states
    "STATE_MAXIMIZED_VERT"
    "STATE_MAXIMIZED_HORZ"
    "STATE_FULLSCREEN"
    "STATE_SHADED"
    "STATE_ABOVE"
    "STATE_BELOW"
}
 
First appeared in 4.0.0.
ForceFocus [{ win-list }]
Give focus to windows whether they asked for it or not.
  This may occasionally be useful with windows that tell us not to give them
  focus, but still need it and fail to work right without us doing so. The
  optional window list allows specifying which windows will get such treatment.
First appeared in 4.0.0. In prior versions, a variant of this
    functionality was unconditionally enabled.
ForceIcons
This variable indicates that icon pixmaps specified in
  the Icons variable should override any client-supplied pixmaps.
FramePadding pixels
This variable specifies the distance between the titlebar
  decorations (the button and text) and the window frame. The default is 2
  pixels if UseThreeDTitles is not set, 0 if it is set.
GrabServer
Specifies that ctwm should grab the X server (blocking
  all events other than ours) when popping up menus and moving opaque windows.
  See also NoGrabServer. Added in 4.0.0; in previous versions this was the
  default.
IconBackground string [{ win-list }]
This variable specifies the background color of icons,
  and may only be specified inside of a Color or Monochrome list. The optional
  win-list is a list of window names and colors so that per-window colors may be
  specified. See the BorderColor variable for a complete description of the
  win-list. The default is “white”.
IconBorderColor string [{ win-list }]
This variable specifies the color of the border used for
  icon windows, and may only be specified inside of a Color or Monochrome list.
  The optional win-list is a list of window names and colors so that per-window
  colors may be specified. See the BorderColor variable for a complete
  description of the win-list. The default is “black”.
IconBorderWidth pixels
This variable specifies the width in pixels of the border
  surrounding icon windows. The default is 2.
IconDirectory string
This variable specifies the directory that should be
  searched if a bitmap file cannot be found in any of the directories in the
  bitmapFilePath resource.
IconFont string
This variable specifies the font to be used to display
  icon names within icons. The default is “variable”.
IconForeground string [{ win-list }]
This variable specifies the foreground color to be used
  when displaying icons, and may only be specified inside of a Color or
  Monochrome list. The optional win-list is a list of window names and colors so
  that per-window colors may be specified. See the BorderColor variable for a
  complete description of the win-list. The default is
  “black”.
IconifyByUnmapping [{ win-list }]
This variable indicates that windows should be iconified
  by being unmapped without trying to map any icons. This assumes that the user
  is will remap the window through the icon manager, the f.warpto function, or
  the TwmWindows menu. If the optional win-list is provided, only those windows
  will be iconified by simply unmapping. Windows that have both this and the
  IconManagerDontShow options set may not be accessible if no binding to the
  TwmWindows menu is set in the user’s startup file.
IconifyStyle string
Where string is either "normal",
  "mosaic", "zoomin", "zoomout" or
  "sweep". Tells ctwm to use some fancy graphical effects when
  iconifying windows.
IconJustification string
Where string is either "left",
  "center" or "right". Tells ctwm how to justify the icon
  image against the icon title (if any).
IconManagerBackground string [{ win-list }]
This variable specifies the background color to use for
  icon manager entries, and may only be specified inside of a Color or
  Monochrome list. The optional win-list is a list of window names and colors so
  that per-window colors may be specified. See the BorderColor variable for a
  complete description of the win-list. The default is
  “white”.
IconManagerDontShow [{ win-list }]
This variable indicates that the icon manager should not
  display any windows. If the optional win-list is given, only those windows
  will not be displayed. This variable is used to prevent windows that are
  rarely iconified (such as xclock or xload) from taking up space in the icon
  manager.
IconManagerFont string
This variable specifies the font to be used when
  displaying icon manager entries. The default is
  “variable”.
IconManagerForeground string [{ win-list }]
This variable specifies the foreground color to be used
  when displaying icon manager entries, and may only be specified inside of a
  Color or Monochrome list. The optional win-list is a list of window names and
  colors so that per-window colors may be specified. See the BorderColor
  variable for a complete description of the win-list. The default is
  “black”.
IconManagerGeometry string [ columns ]
This variable specifies the geometry of the icon manager
  window. The string argument is standard geometry specification that indicates
  the initial full size of the icon manager. The icon manager window is then
  broken into columns pieces and scaled according to the number of entries in
  the icon manager. Extra entries are wrapped to form additional rows. The
  default number of columns is 1.
IconManagerHighlight string [{ win-list }]
This variable specifies the border color to be used when
  highlighting the icon manager entry that currently has the focus, and can only
  be specified inside of a Color or Monochrome list. The optional win-list is a
  list of window names and colors so that per-window colors may be specified.
  See the BorderColor variable for a complete description of the win-list. The
  default is “black”.
IconManagers { iconmgr-list }
This variable specifies a list of icon managers to
  create. Each item in the iconmgr-list has the following format:
    "winname" ["iconname"] "geometry" columns
 
where winname is the name of the windows that should be put into
    this icon manager, iconname is the name of that icon manager window’s
    icon, geometry is a standard geometry specification, and columns is the
    number of columns in this icon manager as described in IconManagerGeometry.
    For example:
IconManagers
{
    "XTerm"  "=300x5+800+5"  5
    "myhost" "=400x5+100+5"  2
}
 
Clients whose name or class is “XTerm” will have an
    entry created in the “XTerm” icon manager. Clients whose name
    was “myhost” would be put into the “myhost” icon
    manager.
IconManagerShadowDepth pixels
This variable specifies the depth of the shadow ctwm uses
  for 3D IconManager entries, when UseThreeDIconManagers is selected.
IconManagerShow { win-list }
This variable specifies a list of windows that should
  appear in the icon manager. When used in conjunction with the
  IconManagerDontShow variable, only the windows in this list will be shown in
  the icon manager.
IconMenuDontShow { win-list }
Don’t show the name of these windows in the
  TwmIcons menu.
IconRegion geomstring vgrav hgrav gridwidth gridheight [iconjust]
    [iconregjust] [iconregalign] [{ win-list }]
This variable specifies an area on the root window in
  which icons are placed if no specific icon location is provided by the client.
  The geomstring is a quoted string containing a standard geometry
  specification. If more than one IconRegion lines are given, icons will be put
  into the succeeding icon regions when the first is full. The vgrav argument
  should be either North or South and is used to control whether icons are first
  filled in from the top or bottom of the icon region. Similarly, the hgrav
  argument should be either East or West and is used to control whether icons
  should be filled in from left or from the right. Icons are laid out within the
  region in a grid with cells gridwidth pixels wide and gridheight pixels high.
  The optional win-list argument tells ctwm that if such a window is iconified,
  and there is enough room in this icon region for its icon, then place it here.
  The optional iconjust, iconregjust and iconregalign can be used to give
  specific values of IconJustification, IconRegionJustification and
  IconRegionAlignement for this IconRegion.
IconRegionAlignement string
Where string is either "top",
  "center" "bottom" or "border". Tells ctwm how to
  align icons inside their place in the IconRegion. If “border” is
  given, the justification will be “top” if the icon region
  gravity is “north” and “bottom” if the icon region
  gravity is “south”.
IconRegionJustification string
Where string is either "left",
  "center" "right" or "border". Tells ctwm how to
  justify icons inside their place in the IconRegion. If “border”
  is given, the justification will be “left” if the icon region
  gravity is “west” and “right” if the icon region
  gravity is “east”.
Icons { win-list }
This variable specifies a list of window names and the
  bitmap filenames that should be used as their icons. For example:
Icons
{
    "XTerm"  "xterm.icon"
    "xfd"    "xfd_icon"
}
 
Windows that match “XTerm” and would not be
    iconified by unmapping, would try to use the icon bitmap in the file
    “xterm.icon”.If ForceIcons is specified, this bitmap will be
    used even if the client has requested its own icon pixmap.
IconSize string
(Only if built with USE_EWMH) string is of the form
  "<width>x<height>" or "size" for a square
  size. This indicates the preferred size of icons selected from the EWMH window
  property _NET_WM_ICON. If an icon with the exact size is not available, one
  with the nearest (area) size will be chosen.
First appeared in 4.0.0.
IgnoreCaseInMenuSelection
Used when moving the pointer inside a menu with the
  keyboard. When you type a letter, the pointer goes to the next entry beginning
  with this letter. If IgnoreCaseInMenuSelection is present, this selection
  ignores the case of this first letter.
IgnoreLockModifier
If present, all bindings (buttons and keys) will ignore
  the LockMask. Useful if you often use caps lock, and don’t want to
  define twice all your bindings.
IgnoreModifier
All bindings (buttons and keys) will ignore the modifiers
  you specified. It is useful when you use caps locks or num locks. You
  don’t need IgnoreLockModifier any more with this option.
IgnoreModifier { lock m2 }
 
IgnoreTransient
List of windows for which to ignore transients.
IgnoreTransient { "Wine" }
 
InterpolateMenuColors
This variable indicates that menu entry colors should be
  interpolated between entry specified colors. In the example below:
Menu "mymenu"
{
    "Title"     ("black":"red")     f.title
    "entry1"                        f.nop
    "entry2"                        f.nop
    "entry3"    ("white":"green")   f.nop
    "entry4"                        f.nop
    "entry5"    ("red":"white")     f.nop
}
 
the foreground colors for “entry1” and
    “entry2” will be interpolated between black and white, and the
    background colors between red and green. Similarly, the foreground for
    “entry4” will be half-way between white and red, and the
    background will be half-way between green and white.
MakeTitle { win-list }
This variable specifies a list of windows on which a
  titlebar should be placed and is used to request titles on specific windows
  when NoTitle has been set.
MapWindowBackground color [{ win-list }]
This variable specifies the background colors to use for
  small windows in the workspace map window and may only be specified inside of
  a Color or Monochrome list. The optional win-list is a list of window names
  and colors so that per-window colors may be specified. If there is neither
  MapWindowBackground, nor MapWindowForeground the window title colors are
  used.
MapWindowCurrentWorkSpace { border_color [background] [foreground]
    [bitmap] }
Specify the appearence of the map window corresponding to
  the current workspace.
MapWindowDefaultWorkSpace { border_color [background] [foreground]
    [bitmap] }
Specify the appearence of the map window corresponding to
  the workspaces other than the current workspace when no root background
  information has been provided to ctwm in the WorkSpace command. Not used in
  others cases.
MapWindowForeground color [{ win-list }]
This variable specifies the foreground colors to use for
  small windows in the workspace map window and may only be specified inside of
  a Color or Monochrome list. The optional win-list is a list of window names
  and colors so that per-window colors may be specified. If there is neither
  MapWindowBackground, nor MapWindowForeground the window title colors are
  used.
MaxIconTitleWidth width
The integer argument tells ctwm the maximun width to use
  for an icon title. If an icon title is larger than width, it is
  truncated.
MaxWindowSize string
This variable specifies a geometry in which the width and
  height give the maximum size for a given window. This is typically used to
  restrict windows to the size of the screen. The default is
  “30000x30000”.
MenuBackground string
This variable specifies the background color used for
  menus, and can only be specified inside of a Color or Monochrome list. The
  default is “white”.
MenuFont string
This variable specifies the font to use when displaying
  menus. The default is “variable”.
MenuForeground string
This variable specifies the foreground color used for
  menus, and can only be specified inside of a Color or Monochrome list. The
  default is “black”.
MenuShadowColor string
This variable specifies the color of the shadow behind
  pull-down menus and can only be specified inside of a Color or Monochrome
  list. The default is “black”.
MenuShadowDepth pixels
This variable specifies the depth of the shadow ctwm uses
  for 3D menus, when UseThreeDMenus is selected.
MenuTitleBackground string
This variable specifies the background color for f.title
  entries in menus, and can only be specified inside of a Color or Monochrome
  list. The default is “white”.
MenuTitleForeground string
This variable specifies the foreground color for f.title
  entries in menus and can only be specified inside of a Color or Monochrome
  list. The default is “black”.
Monochrome { colors }
This variable specifies a list of color assignments that
  should be made if the screen has a depth of 1. See the description of
  Color.
MoveDelta pixels
This variable specifies the number of pixels the pointer
  must move before the f.move function starts working. Also see the f.deltastop
  function. The default is zero pixels.
MovePackResistance pixels
This variable specifies the number of pixels of the
  movepack and movepush resistance. See f.movepack and f.movepush.
MoveOffResistance pixels
This variable specifies the number of pixels of the
  moveoff resistance. If pixels is positive, DontMoveOff will only prevent you
  from going off the edge if you’re within n pixels off the edge. If you
  go further, DontMoveOff gives up and lets you go as far as you wish.
  f.forcemove still allows you to totally ignore DontMoveOff. A negative value
  puts you back into “never moveoff” mode (it’s the
  default).
MWMIgnore
Sets Motif window manager hints ctwm will ignore. The
  following example shows all the valid options:
MWMIgnore
{
    # en/disable window borders
    "DECOR_BORDER"
    # en/disable titlebars
    "DECOR_TITLE"
}
 
First appeared in 4.0.0.
NoBackingStore
This variable indicates that ctwm’s menus should
  not request backing store to minimize repainting of menus. This is typically
  used with servers that can repaint faster than they can handle backing store.
  See also BackingStore. As of 4.0.0 this is the default.
NoBorder { win-list }
These windows won’t have borders. If you want no
  borders on all windows, use the BorderWidth keyword.
NoCaseSensitive
This variable indicates that case should be ignored when
  sorting icon names in an icon manager. This option is typically used with
  applications that capitalize the first letter of their icon name.
NoDecorateTransients
Specify that transient windows (i.e., windows with a
  WM_TRANSIENT_FOR property set) should be ignored (not given decorations) by
  ctwm. See also DecorateTransients. Added in 4.0.0; in previous versions this
  was the default.
NoDefaults
This variable indicates that ctwm should not supply the
  default titlebuttons and bindings. This option should only be used if the
  startup file contains a completely new set of bindings and definitions.
NoGrabServer
This variable indicates that ctwm should not grab the
  server when popping up menus and moving opaque windows. As of 4.0.0 this is
  the default.
NoHighlight [{ win-list }]
This variable indicates that borders should not be
  highlighted to track the location of the pointer. If the optional win-list is
  given, highlighting will only be disabled for those windows. When the border
  is highlighted, it will be drawn in the current BorderColor. When the border
  is not highlighted, it will be stippled with an gray pattern using the current
  BorderTileForeground and BorderTileBackground colors.
NoIconTitle [{ win-list }]
This variable indicates that icons should not display the
  icon name of the client. If the optional win-list is given, only those clients
  will not have icon titles.
NoIconManagerFocus
This variable indicates that ctwm will not set the focus
  on the corresponding window when the pointer is in an IconManager.
NoIconManagers
This variable indicates that no icon manager should be
  created.
NoImagesInWorkSpaceManager
This variable turns off displaying of background images
  in the WorkSpaceMap. Instead only the colors defined in WorkSpaces will be
  used as background in the WorkSpaceMap.
NoMenuShadows
This variable indicates that menus should not have drop
  shadows drawn behind them. This is typically used with slower servers since it
  speeds up menu drawing at the expense of making the menu slightly harder to
  read.
NoOpaqueMove [{ window-list }]
The counterpart of OpaqueMove. See OpaqueMove.
NoOpaqueResize [{ window-list }]
The counterpart of OpaqueResize. See OpaqueResize.
NoRaiseOnDeiconify
This variable indicates that windows that are deiconified
  should not be raised.
NoRaiseOnMove
This variable indicates that windows should not be raised
  when moved. This is typically used to allow windows to slide underneath each
  other.
NoRaiseOnResize
This variable indicates that windows should not be raised
  when resized. This is typically used to allow windows to be resized underneath
  each other.
NoRaiseOnWarp
This variable indicates that windows should not be raised
  when the pointer is warped into them with the f.warpto function. If this
  option is set, warping to an occluded window may result in the pointer ending
  up in the occluding window instead the desired window (which causes unexpected
  behavior with f.warpring).
NoRestartPreviousState
Don’t attempt to regenerate the state the screen
  was in before the previous window manager was shut down. See
  RestartPreviousState for details. Added in 4.0.0; in previous versions this
  was the default.
NoSaveUnders
This variable indicates that menus should not request
  save-unders to minimize window repainting following menu selection. It is
  typically used with displays that can repaint faster than they can handle
  save-unders.
NoShowOccupyAll
This variable specifies that OccupyAll windows
  won’t be displayed in the WorkSpaceMap window.
NoSortIconManager
Specifies that entries in the icon manager should be
  appended in the order they show up. See also SortIconManager. Added in 4.0.0;
  in previous versions this was the default.
NoStackMode [{ win-list }]
This variable indicates that client window requests to
  change stacking order should be ignored. If the optional win-list is given,
  only requests on those windows will be ignored. This is typically used to
  prevent applications from relentlessly popping themselves to the front of the
  window stack.
NoTitle [{ win-list }]
This variable indicates that windows should not have
  titlebars. If the optional win-list is given, only those windows will not have
  titlebars. MakeTitle may be used with this option to force titlebars to be put
  on specific windows.
NoTitleFocus
This variable indicates that ctwm should not set keyboard
  input focus to each window as it is entered. Normally, ctwm sets the focus so
  that focus and key events from the titlebar and icon managers are delivered to
  the application. If the pointer is moved quickly and ctwm is slow to respond,
  input can be directed to the old window instead of the new. This option is
  typically used to prevent this “input lag” and to work around
  bugs in older applications that have problems with focus events.
NoTitleHighlight [{ win-list }]
This variable indicates that the highlight area of the
  titlebar, which is used to indicate the window that currently has the input
  focus, should not be displayed. If the optional win-list is given, only those
  windows will not have highlight areas. This and the SqueezeTitle options can
  be set to substantially reduce the amount of screen space required by
  titlebars.
NoWarpToMenuTitle
This variable indicates that the cursor should not be
  warped to the title of a menu which does not have room to drop down below the
  current cursor position.
Occupy { occupy-list }
This variable specifies which windows occupy which
  workspaces at startup.
occupy-list consists of entries of the form :
        [Window]   win-name  { wspc1 wspc2 ... }
or      Workspace  wspc-name { win1  win2 ...  }
 
Example :
Occupy
{
               "xload"   {"all"}
    Window     "xterm"   {"here" "there" "elsewhere"}
               "xv"      {"images"}
    WorkSpace  "images"  {"xloadimage"}
}
 
If all is given for the workspace name (in either form), the named
    window[s] will be put in all workspaces as if they were listed in OccupyAll.
    If the workspace name begins with ws:, the workspace name will be looked up
    without the prefix first. That is, if the given name is ws:abc, it will
    first look for a workspace called abc, and assign to that if found. Else it
    will fall back to looking for the name ws:abc.
Note : The Occupy declaration should come after the WorkSpaces
    declaration.
OccupyAll { window-list }
This variable specifies a list of windows that will
  occupy all workspaces at startup.
window-list is a list of window names.
Example :
OccupyAll
{
    "xload"
    "xbiff"
    "xconsole"
}
 
Note : The OccupyAll declaration should come after the WorkSpaces
    declaration.
OnTopPriority [Icons] priority [ { win-list } ]
ctwm allows you to put windows in several overlapping
  priority planes going from -8 to +8, which makes it possible to have windows
  that stay on top or that are kept in the background. If win-list is present,
  it specifies which windows should be put in the priority plane. Else the
  priority sets the default value to use (the default default is 0). The Icons
  parameter, if present, indicates that the preference described applies to
  icons rather than to windows.
Example:
OnTopPriority Icons -1  # place icons a little in the background
OnTopPriority Icons 1   # place mail icons on top of normal windows
{
    "Exmh"
    "xbiff"
}
OnTopPriority 8         # keep these always on top of other windows
{
    "Emacs Icon Manager" "WorkSpaceManager"
    "TWM Icon Manager" "XDaliClock"
}
 
First appeared in 4.0.0.
OpaqueMove [{ window-list }]
This variable indicates that the f.move function should
  actually move the window instead of just an outline so that the user can
  immediately see what the window will look like in the new position. This
  option is typically used on fast displays (particularly if NoGrabServer is
  set). The optional window list parameter indicates that only windows in this
  list should actually be moved in opaque mode. The NoOpaqueMove counterpart is
  also available.
As of 4.0.0 this is enabled by default.
OpaqueMoveThreshold threshold
The integer parameter is a percentage and indicates that
  only windows (elligible for opaque moving) with a surface smaller than this
  percentage of the surface of the screen should actually be moved in opaque
  mode. The default is 200. Since 4.0.0, values >= 200 are treated as
  infinity, causing windows to always OpaqueMove if eligible.
OpaqueResize [{ window-list }]
The opaque version of resize. Extremely resource
  intensive, but beautiful with fast server/client/network. See OpaqueMove. The
  NoOpaqueResize counterpart is also available. As of 4.0.0 this is enabled by
  default.
OpaqueResizeThreshold threshold
The resize version of OpaqueMoveThreshold. The default is
  1000. Since 3.8.1, values >= 1000 are treated as infinity, causing windows
  to always OpaqueResize if eligible.
OpenWindowTimeout seconds
seconds is an integer representing a number of second.
  When a window tries to open on an unattended display, it will be automatically
  mapped after this number of seconds.
PackNewWindows
Use f.movepack algorithm instead of f.move when opening a
  new window.
Pixmaps { pixmaps }
This variable specifies a list of pixmaps that define the
  appearance of various images. Each entry is a keyword indicating the pixmap to
  set, followed by a string giving the name of the bitmap file. The following
  pixmaps may be specified:
Pixmaps
{
        TitleHighlight  "gray1"
#       TitleHighlight  "supman%.xbm"
}
 
The default for TitleHighlight is to use an even stipple
  pattern.
PixmapDirectory path
This variable specifies the path where ctwm looks to find
  non-X11 bitmap files. Whenever you want to use a image file that is not an X11
  bitmap, specify : xpm:filename for xpm files, xwd:filename for xwd files,
  jpeg:file for jpeg file, or |command for an on the fly generated xwd file. Use
  the % character to specify an animation. path can be a colon separated list of
  directories. Example :
PixmapDirectory  "/usr/lib/X11/twm"
Icons
{
    "Axe"    "xpm:edit.xpm"
    "xterm"  "xpm:ball%.xpm"
}
 
N.B This is only valid if your version of ctwm has been compiled
    with the right extension (XPM or JPEG).
PrioritySwitching [Icons] { win-list }
Specifies that the windows in win-list can switch
  priority. This means that they can be in plane priority or -priority depending
  on the situation. For instance a window whose priority is 2 will be put into
  plane 2 when raised and plane -2 when lowered, which means that it will
  usually stay on top if you raise another window, but can still be lowered if
  its priority is temporarily too high for your liking. If Icons is specified,
  it means that the preference applies to icons rather than windows. See also
  the f.priorityswitching function for dynamically adding/removing windows at
  runtime.
First appeared in 4.0.0.
PriorityNotSwitching [Icons] { win-list }
As above except that it declares that the default should
  be for windows to be able to switch priority except for the windows in
  win-list which can’t.
First appeared in 4.0.0.
RaiseDelay milliseconds
For windows that are to be automatically raised when the
  pointer enters (see the AutoRaise variable and the f.autoraise function) this
  variable specifies the length of time the pointer should rest in the window
  before it is raised. The default is 0 milliseconds.
RaiseOnClick
If present a window will be raised on top of others when
  clicked on, and the ButtonPress event will be correctly forwarded to the
  client that owns this window (if it asked to). See RaiseOnClickButton.
RaiseOnClickButton button_number
Where button_number is a valid button number (currently 1
  to 11). Specify the button to use for RaiseOnClick.
RaiseWhenAutoUnSqueeze
Windows are raised when auto-unsqueezed (See
  AutoSqueeze).
RandomPlacement [ string1 [ string2 ]]
This variable indicates that windows with no specified
  geometry should be placed in a pseudo-random location instead of having the
  user drag out an outline. If no argument is given, it is interpreted as
  RandomPlacement "on".
string1 may be “on”, “off”,
    “all” or “unmapped”, and string2 is a
    displacement for the pseudo-randomly placed window compared to the previous
    one. The argument “on” or “all” are equivalent,
    and tell ctwm to do this for all such windows, “off”, not to
    do this, and “unmapped”, only for unmapped windows, e.g.
    iconified or not visible in the current workspace. If the second argument
    isn’t given, the displacement +30+30 (30 pixels right and down) is
    used.
As of 4.0.0, “on” is the default if no
    RandomPlacement is specified in the config. Previously “off”
    was default.
ReallyMoveInWorkspaceManager
This keyword tells ctwm to move the actual window when
  the user is moving the small windows in the WorkSpaceMap window. If not
  present the WorkSpaceMap can be used only to modify the occupation of a
  window. Pressing the shift key while dragging a window in the workspace
  manager temporarily toggles this option.
ResizeFont string
This variable specifies the font to be used for in the
  dimensions window when resizing windows. The default is
  “fixed”.
RestartPreviousState
This variable indicates that properties on client windows
  to attempt to regenerate the state that the screen was in before the previous
  window manager was shutdown. This includes using the WM_STATE property to tell
  which windows should be iconified and which should be left visible, and the
  WM_OCCUPATION property to determine in which workspaces a window should be
  visible. As of 4.0.0 this is the default.
ReverseCurrentWorkspace
This variable tells ctwm to reverse the background and
  foreground colors in the small windows in the workspace map for the current
  workspace.
RplaySoundHost string
The host on which sounds should be played. Only
  meaningful when ctwm is built with USE_SOUND; will give a warning otherwise.
  See the SOUNDS section. Added in 4.0.0; prior versions used the SoundHost
  parameter instead.
RplaySounds { sounds-list }
Define what sounds to play on various events through
  rplayd. It contains entries of the form
    "EventName"   "/file/to/play.wav"
 
Only meaningful when ctwm is built with USE_SOUND; it will give a
    warning otherwise. See the SOUNDS section. Note that if this section is
    given in the ctwmrc, the ~/.ctwm-sounds file will not be parsed. First
    appeared in 4.0.0.
SaveColor { colors-list }
This variable indicates a list of color assignments to be
  stored as pixel values in the root window property _MIT_PRIORITY_COLORS.
  Clients may elect to preserve these values when installing their own colormap.
  Note that use of this mechanism is a way for an application to avoid the
  “technicolor” problem, whereby useful screen objects such as
  window borders and titlebars disappear when a program’s custom colors
  are installed by the window manager. For example:
SaveColor
{
    BorderColor
    TitleBackground
    TitleForeground
    "red"
    "green"
    "blue"
}
 
This would place on the root window 3 pixel values for borders and
    titlebars, as well as the three color strings, all taken from the default
    colormap.
ShrinkIconTitles
A la Motif shrinking of icon titles, and expansion when
  mouse is inside icon. The old incorrect spelling SchrinkIconTitles is also
  still accepted.
ShortAllWindowsMenus
Don’t show WorkSpaceManager and IconManagers in
  the TwmWindows and TwmAllWindows menus.
ShowIconManager
This variable indicates that the icon manager window
  should be displayed when ctwm is started. It can always be brought up using
  the f.showiconmgr function.
ShowWorkSpaceManager
This variable specifies that the WorkSpaceManager should
  be visible.
SloppyFocus
Use sloppy focus.
SaveWorkspaceFocus
When changing to a workspace, restore the focus to the
  last window that had the focus when you left the workspace by warping the
  mouse into it. This essentially saves the focus window with the workspace and
  restores it automatically when you switch. In many cases, it avoids having to
  reach for the mouse after moving to a new workspace.
SortIconManager
This variable indicates that entries in the icon manager
  should be sorted alphabetically rather than by simply appending new windows to
  the end. As of 4.0.0 this is the default.
SoundHost string
Alias for RplaySoundHost, used in versions prior to
  4.0.0. Unless you need backward compatibility with them, use RplaySoundHost
  instead. This alias will be removed in a future version.
SqueezeTitle [{ squeeze-list }]
This variable indicates that ctwm should attempt to use
  the SHAPE extension to make titlebars occupy only as much screen space as they
  need, rather than extending all the way across the top of the window. The
  optional squeeze-list may be used to control the location of the squeezed
  titlebar along the top of the window. It contains entries of the form:
    "name"  justification num denom
 
where name is a window name, justification is either left, center,
    or right, and num and denom are numbers specifying a ratio giving the
    relative position about which the titlebar is justified. The ratio is
    measured from left to right if the numerator is positive, and right to left
    if negative. A denominator of 0 indicates that the numerator should be
    interpreted as pixels. For compatibility, the pixel-position 0/0 is the
    relative middle of the window (1/2) for center and the relative right side
    of the window (2/2) for right, but this use is not recommended. Use
    "right 2 2" for relative positioning, or "right -1 0"
    for absolute; this makes a difference when dragging the titlebar (see
    f.movetitlebar). For example:
SqueezeTitle
{
    "XTerm"   left    0  0
    "xterm1"  left    1  3
    "xterm2"  left    2  3
    "oclock"  center  1  2
    "emacs"   right   2  2
}
 
The default positioning is left-justified, absolute at 0 pixels.
    The DontSqueezeTitle list can be used to turn off squeezing on certain
    titles.
StartIconified { win-list }
This variable indicates that client windows should
  initially be left as icons until explicitly deiconified by the user. If the
  optional win-list is given, only those windows will be started iconic. This is
  useful for programs that do not support an -iconic command line option or
  resource.
StartInButtonState
Start the WorkSpaceManage in button form. See also
  StartInMapState. Added in 4.0.0.
StartInMapState
This variable specifies that the WorkSpaceManager should
  be started in its map form when created. See also StartInButtonState. As of
  4.0.0 this is the default.
StartSqueezed { win-list }
These windows will first show up squeezed (see
  f.squeeze).
StayUpMenus
Tells ctwm to use stayup menus. These menus will stay on
  the screen when ButtonUp, if either the menu has not yet been entered by the
  pointer, or the current item is a f.title.
StrictWinNameEncoding
Whether to be strict about what encodings we accept for
  window naming properties. Added in 4.0.2.
This is used when translating properties relating to naming
    windows, like WM_NAME. For example, according to the ICCCM, WM_NAME can only
    be a STRING or COMPOUND_TEXT type. However, sloppy programs like Chrome may
    set it to a UTF8_STRING instead. If this var is set, ctwm will reject that,
    as was standard behavior prior to 4.0.2.
SunkFocusWindowTitle
This variable specifies that the title of the focus
  window (if exists) should be sunken instead of raised. Only valid if
  UseThreeDTitles is set.
ThreeDBorderWidth pixels
The width of the 3D border in pixels, if any.
TitleBackground string [{ win-list }]
This variable specifies the background color used in
  titlebars, and may only be specified inside of a Color or Monochrome list. The
  optional win-list is a list of window names and colors so that per-window
  colors may be specified. The default is “white”.
TitleButtonBorderWidth pixels
This variable specifies the width in pixels of the border
  surrounding titlebuttons. This is typically set to 0 to allow titlebuttons to
  take up as much space as possible and to not have a border. The default is 1
  if UseThreeDTitles is not set, 0 if it is set.
TitleButtonShadowDepth pixels
This variable specifies the depth of the shadow ctwm uses
  for 3D title buttons, when UseThreeDTitles is selected.
TitleFont string
This variable specifies the font used for displaying
  window names in titlebars. The default is “variable”.
TitleForeground string [{ win-list }]
This variable specifies the foreground color used in
  titlebars, and may only be specified inside of a Color or Monochrome list. The
  optional win-list is a list of window names and colors so that per-window
  colors may be specified. The default is “black”.
TitleJustification string
This keyword needs a string value. The acceptable values
  are : “left”, “center” and “right”.
  The window titles will be justified according to this in the title
  window.
TitlePadding pixels
This variable specifies the distance between the various
  buttons, text, and highlight areas in the titlebar. The default is 8 pixels if
  UseThreeDTitles is not set, 0 if it is set.
TitleShadowDepth pixels
This variable specifies the depth of the shadow ctwm uses
  for 3D titles, when UseThreeDTitles is selected.
TransientHasOccupation
This variable specifies that transient-for and non-group
  leader windows can have their own occupation potentially different from their
  leader window. The default case is that these windows follow their leader, use
  this keyword if the default action doesn’t please you.
TransientOnTop percentage
The parameter (required) is a percentage and tells ctwm
  to put transient (and non-group leader) windows always on top of their leader
  if and only if their surface is smaller than this fraction of the surface of
  their leader. The surface of a window is its width times its weight. The
  default is 30%. Added in 3.0.
UnknownIcon string
This variable specifies the filename of a bitmap file to
  be used as the default icon. This bitmap will be used as the icon of all
  clients which do not provide an icon bitmap and are not listed in the Icons
  list.
UnmapByMovingFarAway { win-list }
These windows will be moved out of the screen instead of
  being unmapped when they become invisible due to a change workspace. This has
  been added because some ill-behaved clients (Frame5) don’t like to be
  unmapped.
UsePPosition string
This variable specifies whether or not ctwm should honor
  program-requested locations (given by the PPosition flag in the
  WM_NORMAL_HINTS property) in the absence of a user-specified position. The
  argument string may have one of three values: "off" (the default)
  indicating that ctwm should ignore the program-supplied position,
  "on" indicating that the position should be used, and
  "non-zero" indicating that the position should used if it is other
  than (0,0). The latter option is for working around a bug in older
  toolkits.
UseSunkTitlePixmap
This makes it so the shadows are inversed for title
  pixmaps when focus is lost. This is similar to having the
  SunkFocusWindowTitle, but it makes your xbm or 3d XPM (if any) sink instead of
  just the whole bar.
UseThreeDBorders
Tells ctwm to use 3D-looking window borders. The width ot
  the 3D borders is ThreeDBorderWidth. The color of the 3D border is
  BorderTileBackground, and if NoHighlight is not selected, the border of the
  Focus window is BorderColor. Setting this automatically unsets
  ClientBorderWidth.
UseThreeDIconManagers
Tells ctwm to use 3D-looking IconManagers if any.
UseThreeDMenus
Tells ctwm to use 3D-looking menus.
UseThreeDTitles
Tells ctwm to use 3D-looking windows titles. In which
  case the default values of TitleButtonBorderWidth, FramePadding, TitlePadding
  and ButtonIndent are set to 0. There are plenty of built-in scalable pixmaps
  for buttons: :xpm:menu, :xpm:dot, :xpm:cross, :xpm:bar, :xpm:vbar,
  :xpm:iconify, :xpm:resize, :xmp:sunkresize, and :xpm:box. There are several
  built-in scalable animations for buttons: %xpm:resize, %xpm:menu-up,
  %xpm:menu-down, %xpm:resize-out-top, %xpm:resize-in-top, %xpm:resize-out-bot,
  %xpm:resize-in-bot, %xpm:maze-out, %xpm:maze-in, %xpm:zoom-out, %xpm:zoom-in,
  and %xpm:zoom-inout. Try them to see what they look like.
UseThreeDWMap
Tells ctwm to use 3D for the small windows in the
  workspace map.
VirtualScreens { geometries-list }
This variable specifies a list of geometries for virtual
  screens. Virtual screens are designed to be used when you have several
  physical screens bound together with the Xinerama X extension.
geometries-list is a list of valid geometry strings, that
    correspond to your actual physical screens.
Example :
VirtualScreens
{
    "1280x1024+0+0"
    "1600x1200+1280+0"
}
 
WarpCursor [{ win-list }]
This variable indicates that the pointer should be warped
  into windows when they are deiconified. If the optional win-list is given, the
  pointer will only be warped when those windows are deiconified.
WarpOnDeIconify { win-list }
When ctwm receives a request to map a window, it normally
  just deiconifies it, but if the window is in win-list, it will additionally
  bring it into the current workspace, if necessary. For example
WarpOnDeIconify { "Emacs" }
 
will make sure emacs windows will always popup in the current
    workspace when necessary (typically when the minibuffer or the Help
    frame is in another workspace).
First appeared in 4.0.0.
WarpRingOnScreen
Tells ctwm that f.warpring warps pointer only to windows
  visible in the current workspace.
WarpToDefaultMenuEntry
(Useful only with StayUpMenus) When using StayUpMenus,
  and a menu does stays up, the pointer is warped to the default entry of the
  menu.
WarpUnmapped
This variable indicates that that the f.warpto function
  should deiconify any iconified windows it encounters. This is typically used
  to make a key binding that will pop a particular window (such as xmh), no
  matter where it is. The default is for f.warpto to ignore iconified
  windows.
WindowBox [{ win-list }]
creates a new window called a box, where all the client
  windows that match the windows list are opened in, instead of the root window.
  This is useful to group small windows in the same box (xload for instance)
WindowBox "xloadbox" "320x100+0-0" {
    "xload"
}
 
WindowGeometries { win-list }
Used to give a default geometry to some clients :
WindowGeometries {
    "Mozilla*"       "1000x800+10+10"
    "jpilot*"        "800x600-0-0"
}
 
WindowRegion geomstring vgrav hgrav { win-list }
Similar to IconRegion, but for windows. Note that the
  win-list is not optional.
WindowRing [{ win-list }]
This variable specifies a list of windows along which the
  f.warpring function cycles. If no argument is given, all the windows are in
  the ring.
WindowRingExclude [{ win-list }]
All listed windows will be excluded from the
  WarpRing.
WMgrButtonShadowDepth depth
Control the depth of the shadow of the workspace manager
  buttons.
WMgrButtonStyle string
Sets the style of the workspace manager buttons (when in
  button rather than map state), as well as the buttons in the Occupy window.
  Available options are normal (the default 3d look), style1, style2, and style3
  (which are slightly different 2d looks).
WMgrHorizButtonIndent nb_pixels
Specifies the horizontal space, in pixel, between the
  buttons of the workspace manager (in button mode).
WMgrVertButtonIndent nb_pixels
Specifies the vertical space, in pixel, between the
  buttons of the workspace manager (in button mode).
WorkSpaceFont string
This allows you to specify the font to use for the small
  windows in the workspace manager map. (Try
  -adobe-times-*-r-*--10-*-*-*-*-*-*-*).
WorkSpaceManagerGeometry string [ columns ]
This variable specifies the geometry of the workspace
  manager window. The string argument is standard geometry specification that
  indicates the initial full size of the workspace manager. The columns argument
  indicates the number of columns to use for the workspace manager window.
WorkSpaceManagerGeometry        "360x60+60-0" 8
 
WorkSpaces { workspace-list }
This variable specifies a list of workspaces that are
  created at startup, Where workspace-list is :
name [{bg-button [fg-button] [bg-root] [fg-root] [pixmap-root]}]
 
With:
  
    | bg-button | background color of the corresponding
      button in the workspace manager. | 
  
    | fg-button | foreground color of the corresponding
      button in the workspace manager. | 
  
    | bg-root | background color of the corresponding root
      screen. | 
  
    | fg-root | foreground color of the corresponding root
      screen. | 
  
    | pixmap-root | pixmap to display on the corresponding root
      screen, either the name of a bitmap, xpm:xpmfile, xwd:xwdfile,
      jpeg:jpgfile, or |command_that generates_xwd. | 
Example:
WorkSpaces
{
  "One"   {"#686B9F" "white" "DeepSkyBlue3" "white" "jpeg:shark.jpg"}
  "Two"   {"#619AAE" "white" "firebrick"}
  "Three" {"#727786" "white" "MidnightBlue" "white" "xpm:ball%.xpm"}
  "Four"  {"#727786" "white" "white"        "white"
                                      "|(giftoppm | pnmtoxwd) < 2010.gif"}
  "Five"  {"#727786" "white" "DeepSkyBlue3" "white" "plaid"}
  "Six"   {"#619AAE" "white" "DeepSkyBlue3" "white" "xpm:background1"}
  "Seven" {"#8C5b7A" "white" "chartreuse4"}
  "Eight" {"#686B9F" "white" "MidnightBlue"}
}
 
The WorkSpaces declaration should come before the Occupy or
    OccupyAll declarations. The maximum number of workspaces is 32.
Each workspace also has a label, which is displayed in the
    WorkSpaceManager window when it is in button state. By moving the mouse
    cursor over a button and typing letters and/or backspace, you may edit the
    label. The name is unaffected. Functions that look up workspaces by name
    also look at the label.
XMoveGrid number
This variable specifies the value to use to constrain
  window movement. When moving windows around, the x coordinate will always be a
  multiple of this variable. Default is 1. f.forcemove ignores this
  variable.
XorValue number
This variable specifies the value to use when drawing
  window outlines for moving and resizing. This should be set to a value that
  will result in a variety of distinguishable colors when exclusive-or’ed
  with the contents of the user’s typical screen. Setting this variable
  to 1 often gives nice results if adjacent colors in the default colormap are
  distinct. By default, ctwm will attempt to cause temporary lines to appear at
  the opposite end of the colormap from the graphics.
YMoveGrid number
This variable specifies the value to use to constrain
  window movement. When moving windows around, the y coordinate will always be a
  multiple of this variable. Default is 1. f.forcemove ignores this
  variable.
Zoom [ count ]
This variable indicates that outlines suggesting movement
  of a window to and from its iconified state should be displayed whenever a
  window is iconified or deiconified. The optional count argument specifies the
  number of outlines to be drawn. The default count is 8.
The following variables must be set after the fonts have been
    assigned, so it is usually best to put them at the end of the variables or
    beginning of the bindings sections:
ChangeWorkspaceFunction function
This variable specifies the function to be executed when
  the user change the current workspace (zap).
DefaultFunction function
This variable specifies the function to be executed when
  a key or button event is received for which no binding is provided. This is
  typically bound to f.nop, f.beep, or a menu containing window
  operations.
DeIconifyFunction function
This variable specifies the function to be executed when
  a window is deiconified.
IconifyFunction function
This variable specifies the function to be executed when
  a window is iconified.
WindowFunction function
This variable specifies the function to execute when a
  window is selected from the TwmWindows menu. If this variable is not set, the
  window will be deiconified and raised.
After the desired variables have been set, functions may be attached to
  titlebuttons and key and pointer buttons. Titlebuttons may be added from the
  left or right side and appear in the titlebar from left-to-right according to
  the order in which they are specified. Key and pointer button bindings may be
  given in any order.
Titlebuttons specifications must include the name of the pixmap to use in the
  button box and the function to be invoked when a pointer button is pressed
  within them:
LeftTitleButton "bitmapname" = function
 
or
LeftTitleButton "bitmapname" {
    Buttoni = modlist : function
    ...
    Buttonj = function
}
 
or
RightTitleButton "bitmapname" = function
 
or
RightTitleButton "bitmapname" {
    Buttoni = modlist : function
    ...
    Buttonj = function
}
 
The bitmapname may refer to one of the built-in bitmaps (which are
    scaled to match TitleFont) by using the appropriate colon-prefixed name
    described above.
The pointer button specifications come in two forms, with a
    modifier list or without. When the specification comes without a modifier
    list, it’s used for the case when no modifiers are used. In other
    words, the following two lines are equivalent:
Key and pointer button specifications must give the modifiers that must be
  pressed, over which parts of the screen the pointer must be, and what function
  is to be invoked. Keys are given as strings containing the appropriate keysym
  name; buttons are given as the keywords Button1-Button11:
"FP1"   = modlist : context : function
Button1 = modlist : context : function
 
A user who wanted to be able to manipulate windows from the
    keyboard could use the following bindings:
"F1"    =       : all : f.iconify
"F2"    =       : all : f.raiselower
"F3"    =       : all : f.warpring "next"
"F4"    =       : all : f.warpto "xmh"
"F5"    =       : all : f.warpto "emacs"
"F6"    =       : all : f.colormap "next"
"F7"    =       : all : f.colormap "default"
"F20"   =       : all : f.warptoscreen "next"
"Left"  = m     : all : f.backiconmgr
"Right" = m | s : all : f.forwiconmgr
"Up"    = m     : all : f.upiconmgr
"Down"  = m | s : all : f.downiconmgr
 
ctwm provides many more window manipulation primitives than can be
    conveniently stored in a titlebar, menu, or set of key bindings. Although a
    small set of defaults are supplied (unless the NoDefaults is specified),
    most users will want to have their most common operations bound to key and
    button strokes. To do this, ctwm associates names with each of the
    primitives and provides user-defined functions for building higher level
    primitives and menus for interactively selecting among groups of
  functions.
The modlist allows specifying different bindings for a button or key when
  modifiers are applied. The list of recognized modifier names (abbreviated) are
  shift (s), control (c), lock (l), alter1 (a1), alter2 (a2), alter3 (a3),
  alter4 (a4), alter5 (a5), meta (m), mod1 (m1), mod2 (m2), mod3 (m3), mod4
  (m4), and mod5 (m5). Multiple modifiers may be applied to a single line by
  combining them with a vertical bar (|). For example:
# Open the "top" menu with a Button1 (usually left mouse button) click in
# the root window
Button1 =        : root : f.menu "top"
# Open the "top2" menu with shift-click
Button1 =     s  : root : f.menu "top2"
# And "top3" when control-shift-click
Button1 = c | s  : root : f.menu "top3"
 
The lock modifier refers to CapsLock. meta is generally your Alt
    key. mod1 is the same as meta. mod2..5 can have various special meanings;
    try running xmodmap -pm to see how your X server is mapping things (the
    xkeycaps program may also be useful). The alter1..5 modifiers refer to ctwm
    alternate keymaps; see the description of f.altkeymap below for details.
Note that if you’re using the m4 preprocessor, most
    implementations define a shift macro internally, so using that as a modifier
    will silently fail to work right. To get around it, you’ll need to
    quote it so that m4 passes it through as a literal string: `shift'.
The context lets you specify which mappings apply based on where
    the pointer currently is on the screen. The available options are window
    (w), title (t), icon (i), root (r), frame (f), workspace (no abbreviation),
    iconmgr (m), and alter (a). Like the modifiers above, they may be combined
    with a vertical bar, which allows you to bind an action in multiple contexts
    at once. Alternately, all can be given for the context to specify that the
    binding should happen everywhere. It’s equivalent to combining all
    the choices (except alter, which is special).
The alter context allows binding the function when in the
    alternate context; see the f.altcontext function below for details.
There is an additional possible magical value for context; if you
    provide a quoted string (e.g., "MyXterm") for the context of a key
    (but not button) binding, then that binding will trigger the given function
    in window context to all windows matching that name. e.g.,
# Pressing "F1" anywhere on the screen will cause all windows with name
# "xterm" to raise themselves.
"F1" = : "xterm" : f.raise
 
Beware that this can have odd side effects if multiple windows are
    matched, especially if the function can conflict one with the other (e.g.,
    in the example above, if two "xterm" windows overlap each
  other).
The function in a binding is any of the f. keywords described below. For
  example, the default startup file contains the following bindings:
Button1 =   : root          : f.menu "TwmWindows"
Button1 = m : window | icon : f.function "move-or-lower"
Button2 = m : window | icon : f.iconify
Button3 = m : window | icon : f.function "move-or-raise"
Button1 =   : title         : f.function "move-or-raise"
Button2 =   : title         : f.raiselower
Button1 =   : icon          : f.function "move-or-iconify"
Button2 =   : icon          : f.iconify
Button1 =   : iconmgr       : f.iconify
Button2 =   : iconmgr       : f.iconify
 
User-defined functions contain the name by which they are
    referenced in calls to f.function and a list of other functions to execute.
    For example:
Function "move-or-lower"    { f.move f.deltastop f.lower }
Function "move-or-raise"    { f.move f.deltastop f.raise }
Function "move-or-iconify"  { f.move f.deltastop f.iconify }
Function "restore-colormap" { f.colormap "default" f.lower }
 
The function name must be used in f.function exactly as it appears
    in the function specification.
In the descriptions below, if the function is said to operate on
    the selected window, but is invoked from a root menu, the cursor will be
    changed to the Select cursor and the next window to receive a button press
    will be chosen:
! string
This is an abbreviation for f.exec string.
f.addtoworkspace string
This function adds the selected window to the workspace
  whose name is string.
f.adoptwindow
This function asks for the user to select a window with
  the mouse, and then adopt this window if it doesn’t belong to the
  current ctwm. Useful only with the -w flag.
f.altcontext
Set the alternate context. The next key or button event
  ctwm receives will be interpreted using the alternate context. To define
  bindings in the alternate context, use the keyword alter in the context field
  of the binding command. For example:
"Return" = m : all   : f.altcontext
"n" =        : alter : f.nextworkspace
"p" =        : alter : f.prevworkspace
 
f.altkeymap number
Set the alternate keymap number, where number is an
  integer between 1 and 5 inclusive. The next key or button event ctwm receives
  will be interpreted using this alternate keymap. To define bindings in an
  alternate keymap, use the keyword a followed by number in the modifier field
  of the binding command. For example:
"Return" = c : all                  : f.altkeymap "1"
"i" =     a1 : window|icon|iconmgr  : f.iconify
"z" =     a1 : window               : f.zoom
"d" =     a1 : window|icon          : f.delete
"o" =     a1 : window|icon          : f.occupy
"r" =     a1 : window|icon          : f.refresh
 
When using an alternate keymaps, only the root, window, icon and
    iconmgr contexts are allowed.
f.autolower
This function toggles whether or not the selected window
  is lowered whenever the pointer leaves it. See the description of the variable
  AutoLower.
f.autoraise
This function toggles whether or not the selected window
  is raised whenever entered by the pointer. See the description of the variable
  AutoRaise.
f.backiconmgr
This function warps the pointer to the previous column in
  the current icon manager, wrapping back to the previous row if
  necessary.
f.backmapiconmgr
This function warps the pointer in the same manner as
  f.backiconmgr but only stops at windows that are mapped.
f.beep
This function sounds the keyboard bell.
f.bottomzoom
This function stretches the bottom side of the window out
  to the bottom edge of the screen, or restores the original size if the window
  was already bottomzoom’d.
f.changepriority rel-value
Change the priority of a window by rel-value (enclosed
  within double quotes). For instance, to bury a window one level down, you
  would use f.changepriority "-1". See OnTopPriority variable.
First appeared in 4.0.0.
f.changesize string
This function allows you to change the size of the
  focused window. The format of the string must be either "<border>
  <+|-><sizechange>" (where <border> must be one of top,
  bottom, left or right) or "<x size>x<y size>" (where the
  size is the requested new window size). The height of the window can never be
  set/changed to less than the title height + 1 (or 1 if the window has no
  title) and the width can never be set/changed to less than 1.
"Right"  = c|s : all : f.changesize "right +10"
"Left"   = c|s : all : f.changesize "right -10"
"Down"   = c|s : all : f.changesize "bottom +10"
"Up"     = c|s : all : f.changesize "bottom -10"
"F1"     = c|s : all : f.changesize "640x480"
"F2"     = c|s : all : f.changesize "800x600"
"F3"     = c|s : all : f.changesize "1024x768"
 
f.circledown
This function lowers the top-most window that occludes
  another window.
f.circleup
This function raises the bottom-most window that is
  occluded by another window.
f.colormap string
This function rotates the colormaps (obtained from the
  WM_COLORMAP_WINDOWS property on the window) that ctwm will display when the
  pointer is in this window. The argument string may have one of the following
  values: "next", "prev", and "default". It should
  be noted here that in general, the installed colormap is determined by
  keyboard focus. A pointer driven keyboard focus will install a private
  colormap upon entry of the window owning the colormap. Using the click to type
  model, private colormaps will not be installed until the user presses a mouse
  button on the target window.
f.deiconify
This function deiconifies the selected window. If the
  window is not an icon, this function does nothing.
f.delete
This function sends the WM_DELETE_WINDOW message to the
  selected window if the client application has requested it through the
  WM_PROTOCOLS window property. The application is supposed to respond to the
  message by removing the indicated window. If the window has not requested
  WM_DELETE_WINDOW messages, the keyboard bell will be rung indicating that the
  user should choose an alternative method. Note this is very different from
  f.destroy. The intent here is to delete a single window, not necessarily the
  entire application.
f.deleteordestroy
First tries to delete the window (send it
  WM_DELETE_WINDOW message), or kills it, if the client doesn’t accept
  such message.
f.deltastop
This function allows a user-defined function to be
  aborted if the pointer has been moved more than MoveDelta pixels. See the
  example definition given for Function "move-or-raise" at the
  beginning of the section.
f.destroy
This function instructs the X server to close the display
  connection of the client that created the selected window. This should only be
  used as a last resort for shutting down runaway clients. See also
  f.delete.
f.downiconmgr
This function warps the pointer to the next row in the
  current icon manger, wrapping to the beginning of the next column if
  necessary.
f.downworkspace
Goto the workspace immediately underneath the current
  workspace in the workspace manager. If the current workspace is the bottom
  one, goto the top one in the same column. The result depends on the layout of
  the workspace manager.
f.exec string
This function passes the argument string to /bin/sh for
  execution. In multiscreen mode, if string starts a new X client without giving
  a display argument, the client will appear on the screen from which this
  function was invoked. If the string “$currentworkspace” is
  present inside the string argument, it will be substituted with the current
  workspace name.
f.fill string
Where string is either : “right”,
  “left”, “top”, “bottom” or
  “vertical”. The current window is resized in the specified
  direction until it reaches an obstacle (either another window, or the screen
  border). f.fill “vertical” sets the window status to
  “zoomed” and toggles, ie calling it again will reset the
  previous window size.
f.fittocontent
Can be used only with window boxes. The result is to have
  the box have the minimal size that contains all its children windows.
f.focus
This function toggles the keyboard focus of the server to
  the selected window, changing the focus rule from pointer-driven if necessary.
  If the selected window already was focused, this function executes an
  f.unfocus.
f.forcemove
This function is like f.move except that it ignores the
  DontMoveOff variable.
f.forwiconmgr
This function warps the pointer to the next column in the
  current icon manager, wrapping to the beginning of the next row if
  necessary.
f.forwmapiconmgr
This function warps the pointer in the same manner as
  f.forwiconmgr but only stops at windows that are mapped.
f.fullscreenzoom
This function is similar to the f.fullzoom function,
  except that it makes the client window (the part inside the frame) the size of
  the screen, so the window decorations are off-screen. This gives the same
  visual effect as the window covering the whole screen with no decorations. If
  the window is already fullscreenzoom’d, it restores the original
  size.
f.fullzoom
This function resizes the selected window to the full
  size of the screen, or restores the original size if the window was already
  fullzoom’d.
f.function string
This function executes the user-defined function whose
  name is specified by the argument string.
f.gotoworkspace workspace_name
This function warps you to the workspace whose name is
  workspace_name.
f.hbzoom
This function is a synonym for f.bottomzoom.
f.hideiconmgr
This function unmaps the current icon manager.
f.hideworkspacemgr
Unmap the WorkSpace manager.
f.horizoom
This function stretches the window so that it covers the
  whole width of the screen, or restores the original size if the window was
  already horizoom’d.
f.htzoom
This function is a synonym for f.topzoom.
f.hypermove
Use this function to “move” a window
  between 2 captives ctwm (or between a captive and the root ctwm). Of course 2
  ctwms are completely different universes. You have to go in hyperspace to
  achieve this, hence the name.
f.hzoom
This function is a synonym for f.horizoom.
f.iconify
This function iconifies or deiconifies the selected
  window or icon, respectively.
f.identify
This function displays a summary of the name and geometry
  of the selected window. Clicking the pointer or pressing a key in the window
  will dismiss it.
f.initsize
This function resets a window to its initial size given
  by the WM_NORMAL_HINTS hints.
f.jumpdown step
This function is designed to be bound to a key, it moves
  the current window (step * {X,Y}MoveGrid) pixels downward. stopping if the
  window encounters another window or the screen border (ala f.pack).
f.jumpleft step
Leftward equivalent of f.jumpdown.
f.jumpright step
Rightward equivalent of f.jumpdown.
f.jumpup step
Upward equivalent of f.jumpdown.
f.lefticonmgr
This function similar to f.backiconmgr except that
  wrapping does not change rows.
f.leftworkspace
Goto the workspace immediately on the left of the current
  workspace in the workspace manager. If the current workspace is the leftest
  one, goto the rightest one in the same row. The result depends on the layout
  of the workspace manager.
f.leftzoom
This function stretches the left side of the window out
  to the left edge of the screen, or restores the original size if the window
  was already leftzoom’d.
f.lower
This function lowers the selected window.
f.menu string
This function invokes the menu specified by the argument
  string. Cascaded menus may be built by nesting calls to f.menu. When a menu is
  popped up, you can use the arrow keys to move the cursor around it.
  “Down” or space goes down, “Up” goes up,
  “Left” pops down the menu, and “Right” activates
  the current entry. The first letter of an entry name activates this entry (the
  first one if several entries match). If the first letter is ~ then
  Meta-the-second-letter activates it, if this first letter is ^ then
  Control-the-second-letter activates it, and if this first letter is space,
  then the second letter activates it.
f.move
This function drags an outline of the selected window (or
  the window itself if the OpaqueMove variable is set) until the invoking
  pointer button is released. Double clicking within the number of milliseconds
  given by ConstrainedMoveTime warps the pointer to the center of the window and
  constrains the move to be either horizontal or vertical depending on which
  grid line is crossed. To abort a move, press another button before releasing
  the first button.
f.movepack
This function is like f.move except that it tries to
  avoid overlapping of windows. When the moving window begin to overlap with
  another window, the move is stopped. If you go too far over the other window
  (more that MovePackResistance pixels), the move is resumed and the moving
  window can overlap with the other window. Useful to pack windows
  closely.
f.movepush
This function is like f.move except that it tries to
  avoid overlapping of windows. When the moving window begins to overlap with
  another window, the other window is pushed. If you go too far over the other
  window (more that MovePackResistance pixels), there is no push and the moving
  window can overlap with the other window. Only available if OpaqueMove is
  active.
f.moveresize geometry
Takes one string argument which is a geometry with the
  standard X geometry syntax (e.g. 200x300+150-0). Sets the current window to
  the specified geometry. The width and height are to be given in pixel, no base
  size or resize increment are used.
f.movetitlebar
If applied to a squeezed titlebar (see SqueezeTitle) you
  can drag it along the top of the window (a feature which was first found in
  BeOS). The existing justification type is preserved, as is the positioning
  (relative or absolute). This means that a relatively positioned titlebar will
  move when the width of a window changes, whereas an absolutely positioned
  title will not. The default positioning is left-justified, absolute at 0
  pixels.
Button1 = m1 : title : f.movetitlebar
 
f.movetitlebar does nothing if the window has no title, the window
    is squeezed (see f.squeeze), or the title is not squeezed (see
    SqueezeTitle).
f.movetonextworkspace, f.movetonextworkspaceandfollow
Move the window to the next workspace, and optionally
  switch view over to that workspace.
f.movetoprevworkspace, f.movetoprevworkspaceandfollow
Move the window to the previous workspace, and optionally
  switch view over to that workspace.
f.nexticonmgr
This function warps the pointer to the next icon manager
  containing any windows on the current or any succeeding screen.
f.nextworkspace
Goto the next workspace in the list, using the order
  given in the .ctwmrc file.
f.nop
This function does nothing and is typically used with the
  DefaultFunction or WindowFunction variables or to introduce blank lines in
  menus.
f.occupy
This function pops up a window for the user to choose
  which workspaces a window belongs to.
f.occupyall
This function makes the specified window occupy all the
  workspaces.
f.pack string
Where string is either : “right”,
  “left”, “top” or “bottom” The
  current window is moved in the specified direction until it reaches an
  obstacle (either another window, or the screen border). The pointer follows
  the window.
f.pin
Valid only in a root menu. Make a menu permanent on the
  screen. This is a toggle function, if you select it while the menu is already
  permanent, it becomes non-permanent.
f.previconmgr
This function warps the pointer to the previous icon
  manager containing any windows on the current or preceding screens.
f.prevworkspace
Goto the previous workspace in the list, using the order
  given in the .ctwmrc file.
f.priorityswitching
Toggle the window’s switching ability. X-ref
  PrioritySwitching and OnTopPriority variables.
First appeared in 4.0.0.
f.quit
This function causes ctwm to restore the window’s
  borders and exit. If ctwm is the first client invoked from xdm, this will
  result in a server reset.
f.raise
This function raises the selected window.
f.raiseicons
This function raises all the icons in the current
  workspace.
f.raiselower
This function raises the selected window to the top of
  the stacking order if it is occluded by any windows, otherwise the window will
  be lowered.
f.raiseorsqueeze
Raise the window or squeeze it if it’s a double
  click. The time that defines a double click is given by the
  ConstrainedMoveTime variable.
First appeared in 4.0.0.
f.refresh
This function causes all windows to be refreshed.
f.removefromworkspace string
This function removes the selected window from the
  workspace whose name is string.
f.rereadsounds
This function causes the .ctwm-sounds file to be re-read.
  Note that this will not re-read sounds set in RplaySounds in the config
  file. As a result, this function will probably go away in the future when
  .ctwm-sounds support is removed. See the SOUNDS section.
f.rescuewindows
If you somehow managed to move a window out of sight,
  calling this function will check all windows and icons on currently visible
  virtual screens, and those that are (nearly) out of the bounds of their
  virtual screen will be brought completely inside (if that fits).
First appeared in 4.0.0.
f.resize
This function displays an outline of the selected window.
  Crossing a border (or setting AutoRelativeResize) will cause the outline to
  begin to rubber band until the invoking button is released. To abort a resize,
  press another button before releasing the first button.
f.restart
This function kills and restarts ctwm.
f.restoregeometry
Restore the current window geometry to what was saved in
  the last call to f.savegeometry.
f.righticonmgr
This function is similar to f.nexticonmgr except that
  wrapping does not change rows.
f.rightworkspace
Goto the workspace immediately on the right of the
  current workspace in the workspace manager. If the current workspace is the
  rightest one, goto the leftest one in the same row. The result depends on the
  layout of the workspace manager.
f.rightzoom
This function stretches the right side of the window out
  to the right edge of the screen, or restores the original size if the window
  was already rightzoom’d.
f.ring
Selects a window and adds it to the WarpRing, or removes
  it if it was already in the ring. This command makes f.warpring much more
  useful, by making its configuration dynamic.
f.savegeometry
The geometry of the current window is saved. The next
  call to f.restoregeometry will restore this window to this geometry.
f.saveyourself
This function sends a WM_SAVEYOURSELF message to the
  selected window if it has requested the message in its WM_PROTOCOLS window
  property. Clients that accept this message are supposed to checkpoint all
  state associated with the window and update the WM_COMMAND property as
  specified in the ICCCM. If the selected window has not selected for this
  message, the keyboard bell will be rung.
f.separator
Valid only in menus. The effect is to add a line
  separator between the previous and the following entry. The name selector part
  in the menu is not used (but must be present).
f.setbuttonsstate
Set the WorkSpace manager in button state.
f.setmapstate
Set the WorkSpace manager in map state.
f.setpriority "value"
Set the window’s priority to value (enclosed
  between double quotes). If value is directly followed by < or b, the window
  is placed below other windows of the given priority. Otherwise it is placed
  above. See OnTopPriority variable for details.
First appeared in 4.0.0.
f.showbackground
This function unmaps all windows in the current
  workspace. This is a toggle function, if all windows are unmapped, they are
  all remapped. Better bind this function in the root context.
f.showiconmgr
This function maps the current icon manager.
f.showworkspacemgr
Map the WorkSpace manager.
f.slowdownanimation
Decrease AnimationSpeed by 1.
f.sorticonmgr
This function sorts the entries in the current icon
  manager alphabetically. See the variable SortIconManager.
f.speedupanimation
Increase AnimationSpeed by 1.
f.squeeze
f.squeeze squeezes a window to a null vertical size.
  Works only for windows with either a title, or a 3D border (in order to have
  something left on the screen). If the window is already squeezed, it is
  unsqueezed.
f.startanimation
Restart freezed animations (if any).
f.stopanimation
Freeze animations (if any).
f.switchpriority
Switch the window’s priority, independently of its
  ability to switch automatically. X-ref OnTopPriority and PrioritySwitching
  variables.
First appeared in 4.0.0.
f.tinylower, f.tinyraise
These two functions allow you to raise/lower a window
  "one step" at a time. For instance, f.tinyraise will bring the
  current window just above the lowest one that’s hiding it. These two
  functions are not subject to priority-switching.
First appeared in 4.0.0.
f.title
This function provides a centered, unselectable item in a
  menu definition. It should not be used in any other context.
f.toggleoccupation string
This function adds the selected window to the workspace
  whose name is string if it doesn’t already belongs to it, and removes
  it from this workspace if not.
f.togglesound
Toggle sound on/off. See the SOUNDS section.
f.togglestate
Toggle the state of the WorkSpace manager.
f.toggleworkspacemgr
Toggle the presence of the WorkSpaceManager. If it is
  mapped, it will be unmapped and vice versa.
f.topzoom
This function stretches the top side of the window out to
  the top edge of the screen, or restores the original size if the window was
  already topzoom’d.
f.trace string
Used for handling dumping debug output. If a filename is
  given in string, begins writing output to that file; if string is
  "stderr" writes to stderr. If debug file is already open, calling
  f.trace again closes it.
This is probably only useful if you’re doing development on
    ctwm.
f.twmrc
Alias for f.restart.
f.unfocus
This function resets the focus back to pointer-driven.
  This should be used when a focused window is no longer desired.
f.unsqueeze
Is to f.squeeze what f.deiconify is to f.iconify.
First appeared in 4.0.0.
f.upiconmgr
This function warps the pointer to the previous row in
  the current icon manager, wrapping to the last row in the same column if
  necessary.
f.upworkspace
Goto the workspace immediately above the current
  workspace in the workspace manager. If the current workspace is the top one,
  goto the bottom one in the same column. The result depends on the layout of
  the workspace manager.
f.vanish
The specified window vanishes from the current workspace
  if it occupies at least one other WorkSpace. Do nothing in the others
  cases.
f.version
This function causes the ctwm version window to be
  displayed. This window will be displayed until a pointer button is pressed or
  the pointer is moved from one window to another.
f.vlzoom
This function is a synonym for f.leftzoom.
f.vrzoom
This function is a synonym for f.rightzoom.
f.warphere win_name
This function adds the window which has a name or class
  that matches string to the current workspace and warps the pointer to it. If
  the window is iconified, it will be deiconified if the variable WarpUnmapped
  is set or else ignored.
f.warpring string
This function warps the pointer to the next or previous
  window (as indicated by the argument string, which may be "next" or
  "prev") specified in the WindowRing variable.
f.warpto string
This function warps the pointer to the window which has a
  name or class that matches string. If the window is iconified, it will be
  deiconified if the variable WarpUnmapped is set or else ignored.
f.warptoiconmgr string
This function warps the pointer to the icon manager entry
  associated with the window containing the pointer in the icon manager
  specified by the argument string. If string is empty (i.e. ""), the
  current icon manager is chosen.
f.warptoscreen string
This function warps the pointer to the screen specified
  by the argument string. The argument may be a number (e.g. "0" or
  "1"), the word "next" (indicating the current screen plus
  1, skipping over any unmanaged screens), the word "back" (indicating
  the current screen minus 1, skipping over any unmanaged screens), or the word
  "prev" (indicating the last screen visited).
f.winrefresh
This function is similar to the f.refresh function except
  that only the selected window is refreshed.
f.zoom
This function stretches the window so that it covers the
  whole height of the screen, or restores the original size if the window was
  already zoom’d. It’s the vertical counterpart fo f.horizoom;
  perhaps f.vertzoom would be a better name...
