Light years beyond, thanks!

Can you now deal with a key_timer as combos are time sensitive? Also, the remaining questions are - two keys at once. And charging a single key for a time before moving to the next key.

Two keys is an assumption as the engine checks each frame and one at a time, again needing a timer and lastpressed check.

You're Still, a Master and this is AUM worthy - Hail @txesmi.
