When I added support for the No key and Any key events in r332 and r333,
it occurred to me that it wouldn't be difficult to add a kind of "All Arrow Keys" Key which,
when added, would produce 4 events - all 4 arrow keys of course.
Much like the No Key and Any Key, it would have to be selected from the key menu added in r333.

Sounds like a plan.
