It's exactly what I need, Dave. Thank you!
A small question: there is "Enable access for assistive devices" in
Universal Access, what do you think, can any of these devices treat my
fake button as a real button (even if the button don't accepts "first
responder")? Or removing first responder from a button guarantees that
it never be accessible?
