Thank you for replying.

I got your idea. A timer that would count down, and use "key_lastpressed" function for the last input.

But there is some problem remaining. what about "↘", that require both "↓"&"→". And what about holding, say I'm making a guy like GUILE(street fighter).

OK I'll check the AUM for answer or some ider.

Thanks again for the kindheart! wish you happy.
