Messing around with it in length. I did get some where.

In terms of in-game I finally figured out what action bar key bindings match up in the wow client. So i've made progress there.

Also have the in-game macros correct. But IsBoxer is still giving me trouble.

I binded two abilities across all toons
Alt D for "power up" Which does the power infusion on lock and uses arcane power on mages
Alt M for mount up on all toons.

If I press the Alt D button it only broad casts to the current active window, not all of them. That's the issue. Upon trying different settings and things I ended up breaking the M key and it would no longer work, period. Took a while but manage to restore the use of that key. Seems like anytime I need to touch something I break it from inexperience.

All I really need to do is be able to broadcast a key binding to all windows. Thats the procedure I need help with at this point.
