Jamba macros, how to?

[Lokibrth]

I've been reading through the posts on Jamba macros and frankly I can't make heads or tales of it. Maybe what I'm trying to do is not possible and that's why I can't figure it out?

Anyway, what I've been attempting (completely unsuccessfully) is to make macro's that i can place on Master's action bars that will perform both dual actions for my slave and my master and actions just for my slave.

Examples: A button I can click that will make both the master and the slave mount up at the same time.
Have all my healing bar skills of my slave Priest on the right hand action bar of my Master character so I can just click them to trigger heals on myself.

Can Jamba do this or am I stuck having to use another program to tie actions to key bindings?
