I've been looking at the above quoted macro.

I'm trying to figure out what the purpose of the series of "0" of various length and how does the game interpret those. In addition, I've seen a few macros where instead of "0,0" the macro contains the text "1,2". I've looked in Khatovar's macro thread and there are additional examples but I don't see an explanation for what those numbers do.

I'm sure it's some it somehow prioritizes those listed abilities, but trying to figure out how the game interprets those commands so I can apply it and tweak it to my own setup. Thanks!
