Clump of crap is right. I've decided to help you even though you're using Keyclone.

If you haven't checked out this thread, do it now: "FTL and Keyclone Simplified" http://www.dual-boxing.com/showthread.php?t=29115

Basically, each of your guys is going to have a list of hotstrings. Hotstrings map a name to a key combo. When you press a named key on one guy, it's going to resolve the name on the other guys to press in their window. So for example, LBAT on the first guy is 2, but on every other guy LBAT might be Ctrl+Shift+]. In this example, the logic happens when you press 2. It's going to pass 2 to the current window, and then tell the others to press LBAT, which they resolve to Ctrl+Shfit+], which your WoW macro then resolves to something like /cast [target=toon1target] Lightning Bolt ... causing them to cast Lightning bolt on what they have as your current target.

Likewise, you can press Ctrl+Shift+] on any other window and it will pass Ctrl+Shift+] in all windows except for the one set to 2 for LBAT.

In short, there is one Hotstring per toon per spell.
