Keys in the graphical frontends

During the graphical emulation, you can use special key combinations to change modes. The default key mappings are shown below, but if you use -alt-grab then the modifier is Ctrl-Alt-Shift (instead of Ctrl-Alt) and if you use -ctrl-grab then the modifier is the right Ctrl key (instead of Ctrl-Alt):

Ctrl-Alt-f
Toggle full screen
Ctrl-Alt-+
Enlarge the screen
Ctrl-Alt–
Shrink the screen
Ctrl-Alt-u
Restore the screen’s un-scaled dimensions
Ctrl-Alt-n

Switch to virtual console ‘n’. Standard console mappings are:

1
Target system display
2
Monitor
3
Serial port
Ctrl-Alt
Toggle mouse and keyboard grab.

In the virtual consoles, you can use Ctrl-Up, Ctrl-Down, Ctrl-PageUp and Ctrl-PageDown to move in the back log.
