Multiboxing with different classes in one party

Ok im already done my macros for dps and tanking but what should i do with my healer? can i use healbot on my main character(tank) to heal my team with my toon-healer(shaman)?

I don't think your software has a means to pass the mouse automatically that will work with a Healbot setup. You are going to have to use target-based healing macros. IE /cast [@party1] Healing Spell
