|  | During the graphical emulation, you can use special key combinations from | 
|  | the following table to change modes. By default the modifier is Ctrl-Alt | 
|  | (used in the table below) which can be changed with ``-display`` suboption | 
|  | ``mod=`` where appropriate. For example, ``-display sdl, | 
|  | grab-mod=lshift-lctrl-lalt`` changes the modifier key to Ctrl-Alt-Shift, | 
|  | while ``-display sdl,grab-mod=rctrl`` changes it to the right Ctrl key. |
