Scaled viewer mode displays the scaled remote screen in a window with a user defined size.

Fuzzy screen mode combines Server and Viewer scaling to provide reasonable visual comfort and speed even over very slow connections.
Autoscaling mode scales the view to fit the viewer screen.
Normal screen mode (hotkey CTRL+F11) displays the remote screen 1:1.

Additional Hotkeys

Pressing ALT or CTRL send ALT/CTRL directly to the VNCServer, as if the user selected "CTRL DOWN/CTRL UP/ALT DOWN/ALT UP" from the system menu.
