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.
