[wellylug] XLib code

[Chris 'xin' Targett]

I'm writing a xlib based app to emulate Half-Qwerty. This probably isn't
the best place to ask, but I'll ask anyway.
I've found code that re-maps the keypad when you hold down space, but
when you press space the key is registered and a space character is
typed.
Does anybody know of a way to stop the key-press being registered, wait
for another key to be pressed, and if there hasn't been another key
pressed, type space upon release of the key?

Thanks
