Thanks for the help - I guess was trying to make it to complicated

Moving on... I have my "target me" and "assist me" keys working now. I am trying to actually use an ability. Both characters are sages, so I put Telekinetic Throw on the Left quickslot 1 for each character and bound "Alt-1" to cast it in game.

In ISBoxer, I set up a keymap on Sage 1 like this:

Do Assist Me in Sage 1 Key Map->self
Alt+1->all

I bound this all to Ctrl-Shift-T in ISBoxer. When I press Ctrl-Shift-T in-game, the secondary character assists me and selects my target (so that much is working), but neither one of them actually fire an Alt+1.
