Synthesising an UP event after receiving a DOWN from the keyboard, and nothing else for that key for > (repeat delay + a bit more) time looks like a good plan to me, UNLESS there are keys which do report UP when the key is released (as opposed to immediately after the DOWN), and also don't repeat. Unrelated: I have some messages from my laptop, Toshiba Satellite 4070CDT: atkbd.c: Unknown key (set 2, scancode 0x94, in isa0060/serio0) pressed. atkbd.c: Unknown key (set 2, scancode 0xbf, in isa0060/serio0) pressed. atkbd.c: Unknown key (set 2, scancode 0xa1, in isa0060/serio0) pressed.
