I've searched around. This all looks like a foreign language to me. What I want to do is simple.

My action bar goes 1 - 9. I only want to use 1 - 5. So I put the appropriate skills for my lead char in 1 - 5, and the appropriate skills for my slave in 1 - 5.

I don't mind making both chars eat manually, or making the slave follow manually. All I want to do is when I press space, both characters jump, and when I press 1 - 5, they both perform that skill.

And before you flame me, yes, I've done searches. The concept is just too abstract for me.
