# 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.
