Sweet, I didn't even think about the modifiers. I previously had them all bound to CTRL+(F1-F5).

Question: Can the modifier key be only shift, alt, ctrl? Is there a way to make a different key a modifier, for instance F1? so CTRL could remain my macro button, but I would use F1-F5 as modifiers?


EDIT:
Inside the blizzard macro. mod=shift/alt/ctrl. I was asking if it was possible to do mod=F1, or something similar. After checking the macro portion on wowwiki, inapparently it isn't possible.

Does this mean that the method of PiP switching mentioned in the OP is impossible with 5 toons? Since there are only 4 modifier keys?
