| 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. |
