Well I'm not necessarily meaning that it should use the sendkeys function. What I want is that a browser or flash game would recieve a stimulated keypress without the window having to be in focus so the user could do other things. Since it hasn't been implemented into any programs here, I'm doubting its possible.

Doesn't Stapled's Booty Grab bot use the arrow keys to make the player go side to side without the form requiring focus?
