ever consider using the function keys to heal your party members? with my pve group controling the tank priest and mages on follow i'd use F1-F5 as the hotkey to tell the priest which toon in the party needed healing - bind each of those to a single key on the priest client (if F1 then Greater heal macro with alt key alt modifer signifies heal party member 1.... F2 = same macro with shift modifier for second party memeber etc etc... this way u can quickly bind shields / renews / multiple heals to easy to hit hotkeys on your main account.... for just f1-f5 my priest launched greater heals... when i needed a heal in a pinch used ctrl-f1-f5 and that send to a flash heal macro in the same logic alt f1-f5... a shield etc etc... i liked it because was easy to hit didn't have to worry about clicking and losing my current target (oh also disable the select party members hotkeys on that main box else you will lose target
