multi-functional key mod

[Axeanz]

Got the idea from #7125.

About the mod: it changes the way the keypresses get registered. How?
Pushing it in counts as a hit, holding it down counts as an hold. Releasing also counts as a hit and keeping your key untouched also counts as a hold. So any change in the key's state counts as a quick press. This would mean that in theory, you can play anything, including stream-maps, with just 1 key.

No idea if this is possible, but still an idea I felt like suggesting.

I don't really understand what your proposing here

If I understand correctly, the proposal is to affect key input in the way depicted in the following screenshot:

In other words, circles wouldn't respond to key down events, but keypress state change events (in signal processing terms, a click wouldn't be a rising edge, but any edge).

I see. Would need a name that describes this better.
