Sandman Scout Script

I love scripts and have one request. Is there a script where I press a button, it switches to sandman, fires the ball and switches back to my weapon I had out/Scattergun? Thank you.

use autohotkey

What's that?

bind "mouse5" "slot3; +attack2; wait 255; -attack2; lastinv"

I cant make it any faster than that. It requires you to wait that long that after you switch to the bat before you can use the ball.
