Really n00b Macaroon question

I'm finally getting around to setting up more than FuBar and Jamba, and while I use Bartender on my solo main, posts here convinced me to try Macaroon. It looks promising, with a rather large problem: I can't seem to figure out how to set up buttons. I can set up bars, and add buttons to bars, but I'm completely confused about the relationship between buttons, spells, and keybinds. What I'm trying to do is basically create two 12-button actionbars, one using the standard 1-= keys, and one using shift(1-=). From reading various posts, I feel like this shouldn't be too tricky. But I can't figure out how to put spells into the bars. I get into the button interface and it keeps talking about ActionIDs. How do I find the actionid of the spell I want? Am I even on the right screen?

Nevermind, got it figured out once I stopped trying to edit the buttons through the "saved buttons" interface.

New question: Once I get everything set up on my main, is there any way to copy the settings over to my other characters?

macaroom.lua file in the WTF/blah blah/character name folder. Copy it to the other account folders etc.
