Right now I'm using /cast [target=party1-5] lesser healing wave, or /cast [target=mychar1-5] lesser healing wave. Not using any healer addon or anything.

So to clarify, what i was wondering is, if my character set is :
mychar1
mychar2
mychar3
mychar4
mychar5
and i want to switch out mychar1 with mychar6, is there any way to set up my ISBoxer keymaps so it check which char is the active char in the character set? So I wont have to change my key maps everytime i switch one character for another. I know it doesnt matter with /cast [target=party1-5] but that doesnt work in BGs =(
