# Keys in the graphical frontends

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.
