Boxing in BGs?

[chazz]

Using Variable Keystroke Actions you only need one Assist and one Follow key. Then you use one Set Target key (with up to two modifiers if you're triple- or quad-boxing) to change it on the fly ingame. Set up one to four identical key maps and disable the ones that each character slot doesn't use. This way the same key works for all slots and you can just switch character, hit the Set Target key and in a matter of seconds you have defined a new Lead for all your slaves. This works no matter what party member slot they see each other in.

EDIT:
If what I said didn't make sense (been awake for over 24 hours) I could make a short video guide tonight showing you how to do this, if anyone is interested. Right now I need some sleep though.
