Implement hotkeys such as KEY_PLAYPAUSE, KEY_RFKILL

[filipleple]

The problem you're addressing (if any)

Currently, hotkeys that can be identified using libinput debug-events, such as KEY_PLAYPAUSE, KEY_RFKILL, KEY_F21 (disable touchpad) are ignored by Qubes OS.

The solution you'd like

Those hotkeys' functionality could be implemented, as it is in other OS'es.

The value to a user, and who that user might be

Anyone who has a keyboard with such hotkeys might want to be able to take full advantage of it.

How do you propose KEY_PLAYPAUSE to be implemented? dom0 (or dom0 + sys-audio) would somehow have to guess which VM media is playing in and route the event there, which does not seem easy.

The same issue is with the KEY_TOUCHPAD_TOGGLE key.
