Ok so here is my problem...

I run 5 instances of wow and use a main and 4 slaves. Currently when my main dies i have nothing set up to have 1 of the slaves take his place....

Sooo here is what i use to accomplish what i do currently. I use HKN.

This is the macro in WoW...

I have this bound to the 1 key for all instances.

/target focus
/follow
/assist
/stopcasting

What could i set this to so that no matter what window becomes active it switches the slaves to follow and focus/target the new active window?
