During the graphical emulation, you can use special key combinations from
the following table to change modes. By default the modifier is :kbd:`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 :kbd:`Ctrl+Alt+Shift`,
while ``-display sdl,grab-mod=rctrl`` changes it to the right :kbd:`Ctrl` key.
