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:
