sorry, I have no idea what you are trying to do on a high, semantical
I suppose radio/mute/navi key events are something you want to deliver
to one specific client at all times, regardless of any focus. If yes,
adding a new protocol extension to deliver exactly those as semantic
events would be fine.
However, I don't understand what you want with
left/right/down/up/enter. What's wrong with just the standard
wl_keyboard protocol, if those events need to go to the client/surface
currently holding the keyboard focus?
So, what does the "associated with windows" actually mean? Who should
be getting these events?
I don't recall you explaining what HardKey is. Knowing exactly what it
is might help.
