DESCRIPTION :
Input handler for input from devices. <device_id> is a unique address enabling
the editor to handle input from more than one device at a time. The <event>
describes the type of event, button numbers and key modifiers, and the volume
of space affected by the interaction. Main events are button press, movement and
release.
