Self-cast Modifier Petition

The API is still there, just the UI option was removed. It was causing too much confusion with people who had SHIFT-1, CTRL-1, bound to other things by default, which overrides the self cast key.

All you have to do is:
SetActionSelfCastKey("SHIFT")
or
SetActionSelfCastKey("CTRL")

Stick it in a macro or in an addon, and you'll be fine.

Q u o t e:
While it's all fine and dandy that now everytime I log in I have to spam a macro button just to reset my self cast key - I think it's pretty lame that because a "few users" couldn't figure out how to unselect CTRL or otherwise not goof up their UI ~ the rest of us who depended on that built in feature are made to suffer a life of macro spamming.

So, grab the Blizzard interface kit, check out the Hello World tutorial, and throw that line in there. Voila! Now you're an addon author! :)
