* - with ctrl key

* - with altgr key (usually ALT-right)
* - with shift+altgr key

* These keys are usually processed before the above keys. To gain control
* over these keys, you must run the keyboard in raw mode (/dev/kbd) and
* do ALL the processing yourself. The Xserver for instance does it this way.
* The following special keys are currently defined:
*
* CTRL-ALTLEFT-DELETE: Reboot
* CTRL-ALTLEFT-ESCAPE: Call the debugger (if compiled into the kernel)
* CTRL-ALTLEFT-KP+: Switch to next resolution (Xserver only)
* CTRL-ALTLEFT-KP-: Switch to previous resolution (Xserver only)
