more than 2 keys for WoW's Key Bindings?

[-silencer-]

Can AHK or Keyclone do this kind of stuff?

Yes, AHK can remap keys, which *should* be legal since you're not sending multiple keypresses at once, you're just broadcasting a different key to each instance of WoW.

(I'm at work, so this is just pseudo-script)

~F10:: (pressing F10)
For instances of WoW:
ControlSend,,w, %wowid1
ControlSend,,q, %wowid2
ControlSend,,e, %wowid3

This means when you press F10, your main will move forward, your 1st follower will strafe left, and your 2nd follower will strafe right. The tricky part will be the wowid's.. and making sure they're set to the WoW instance you want for the apprpriate key.
