Ok, I used the macro elsegundo has and I have it working-somewhat. When I run up to the mob I hit "2" on my keyboard and the Warr main attacks. Then, I have to hit "2" again for the alt to cast Lightning Bolt. Then if I want to do that again I have to hit "2" twice more.

Shouldn't it work by just hitting the "2" once? If I'm hitting it twice I'm starting/stopping attack on my warrior. I feel like I'm getting closer, can anybody identify what I need to fix?
