If you decide to try it out, I will help you write the script. It's terribly easy, and I'll show you how to make it so it only activates when you run the specific program. You can make single button presses equate to multiple button presses, too, so there's that.

If you decide to go another route, disregard.

I'd be interested. I tried the one below, but for some reason it doesn't work...my character just jumps instead of dodging.

; Remap Left Shift to Right Mouse button and Space
LShift::
Send, {RButton}
Send, {Space}
return
