And no I don’t have one of those little bird thingys.

I have a game that requires that I hit “enter” after every turn. I set it so that all the players are computers, although it still stops after my turn. How can I get it so that the computer thinks I’m hitting the Enter key over and over again when I’m away form the pc? I’m running XP, if that helps.
