Multiple events on long press.

I don't think this was the case in prior versions, or at least I didn't notice it.

When long pressing keys, matching bindings fire their callbacks 10s of times a second. I've had to implement throttling on the code being run by the hotkeys internally to work around.

Either as default, or an option, long presses should not trigger the callback again until release and re-press.
