When I started getting into boxing I was also dismayed to find that I had to stop my clicking ways and become a hotkey user. Do yourself a favor. Try it. Youll never go back.

Heres my advice: dont try to box it. Just pick a character you know and just WIPE HIS BARS. Force yourself to start over. THink about how you play and then start setting up your bars in a way that will compliment the abilities you use the most in the best key positions.

Alternately there are some mouse broadcasting programs =)
