this works in hotkeynet
/cast [target=mouseover, exists, help] [target=focus, help] [] Flash Heal
esp if you use info for script from khatovar's link above
actually i change it in mine to
/cast [mod:alt,target=mouseover, exists, help] Flash Heal; [target=focus, help] [] Flash Heal
but still need region of your unit frames to use or it will mess up and heal mouseover targets that you don't want it to ie party members themselves as apposed to one you want it to when you want it to. Which is why the mouse region it used from his link
What this macro does is if mouse is over certain area on screen send alt plus the key and does a mouseover heal. if no alt sent that means we don't have a mouseover to heal focus if no focus heal target ie the [] and player if none of the above although i think self cast has to be on in settings for the self heal part.
Note that i use grid with it set to sort by name so order is always the same in the unit frames in the mouseover region.
