Hey im new to multiboxing and have got everything setup already.

Im using Jamba and Macaroon to help me do this but im having problems with it.
Ive set it so that I can switch to each character using PiP and with the same key I change focus on each character using a Macro, so now ive got all my chars with my main focused. But how do I make them all cast spells/heals by assisting the focus with minimum hassle? I know I have to use macros to do this, but this will get tedious to do with every single spell I wish to put on my hotbar.. Is there any quick way of doing this?

At first I thought Macaroon would be doing this for me, but Im guessing I was wrong.. Not to sure yet >.>
