hotkeys and stuff : General Discussion

i've tried various programs, but i can't get it to work:

the game is GunZ: The Duel, and what i want to do is, say, press one key, and the comuter simulates the pressing of several keys (so, for example, i'd press '1' and it'd be like changeweapon-changeweapon-dash or something). there are many functional and free hotkey programs, but none of the ones i've tried work in-game; maybe it's because the game uses DirectX, i dunno.

i'm playing legit currently and still having plenty of fun, so if i can't get this to work it's fine
