keyboard-request - event signalling console press of Alt-UpArrow
The keyboard-request event is generated by the Upstart init(8) daemon
when the keyboard request key combination (typically Alt-UpArrow) is
pressed on the console.
The support for this event depends on your kernel configuration.
Suggested use for this event includes spawning a new login console when
pressed, or for secure attention key support.
This event is not handled in the default Upstart configuration.
A task to be run on the keyboard request might use:
