Well, the way I have my current mouseover macro set up in ISBoxer is for it to turn repeater on and off in step 1 and then in step 2 push the key in the healer's window. Then I have it set to execute a step on both push and release, so it does both these steps each time I push the button.

I'm not really familiar with repeater regions. I just got ISBoxer two nights ago. I can poke around a bit with that tonight. Would I be able to make a repeater region that applies to my aforementioned method, as kind of a mask?
