So, the problem I'm having with this system is that while I'm bashing my main FTL assist attack button, my priest is getting alt, shift and control sent to its window. So when I try and pass a click via the region with either alt, control or shift to healbot, healbot gets confused because of the additional FTL modifiers.

My options are a) drop FTL or b) try and rework with invisible click map thingys.

I'm going to try b sometime soon.
