I 5box and im using the keypads to heal my party members.(found this in another thread)

Simply download an addon called Bindpad, it's an addon where you make macros and you bind the macro's directly to a key on ur keyboard.
I set it up like 7,8, 9 heal party1. 4,5, 6 heal party2. 1,2,3 heal party3. 0, Del, Enter heal party4.

It's not perfect but it's working decently.
