You're asking for a way to make the game do things for you while you do things outside the game. It's a pretty weak loophole you're trying to work. Any means you could find for doing this would be easily translated into "legal botting" simply by changing the key it sends to the game.

If you've got better things to do with your time, then do those other things. Otherwise
