I have a holy priest. I have buttons bound to the number pad then a cast sequence on my g1-g5 keys for each toon renew, flash heal, greater heal. My numberpad + is the cast sequence of renew, greater heal, greater heal, flash heal on the tank. My numpad enter does the aoe heal. My numpad 3 does shield and prayer of mending. My numpad 9 does the instant aoe heal. My F1-F5 put shields on people. I never use those keys because I just heal any damage.
