Muscle flexing commit; put the "any key modifier" to work, also exposed
(ugly) in keymap editor. Notes for it works:

- You can use any keyboard key to become modifier now (not mouse buttons)
- But, if this key was assigned to be a regular hotkey, that still gets
triggered, obviously.
- So: only use unused keys for this, like "~" or other special ones?

For test fun: L+K now does animplay.
