First Person Map help

I'm making a first person map where you move with button keys, looks like this:

Forward: W
Left: A
Right: D
180 degree turn: S

I used the goblin merchant method of doing this which means the character you are using isn't selected, the goblin merchant is. My problem is getting my unit to attack. I need a way to make my non selected unit attack preferably using another button.

Any ideas? Thanx.

Anyone??

I'd tell you but then i'd have to kill you.
Just don't tell people you thought of this because i'm using this in my map <:D
