Hmm, yes, but, but... it's the same as for "mouseover": it doesn't work if I bind the macro "/click MyRaidAddon_Group3_Member2" to my button "1", and if I press "1". I mean, my mouse could be anywhere on the screen.
Then, a way to know what unit I am casting on would be to know what button has been activated (by a "/click" command), and to use GetAttribute.
I really feel like I'm wasting your time with stupid questions though :< Maybe I should just quit
