This is as good as any thread to tag along, I have read the macro forums (mostly). And not to ninja his thread but is there a easier way to macro then to write a macro for a slave and rewrite it for each and every other toon. I also use bartender and while I'm making headway into my 5-box I find that two things drive me nuts.
1) Occasionally Shift will xfer through to the box's even though I have a do not pass set for shift and it will cause the default bar to scroll up and stop the abilities of my slaves. I Macro lb's on my shaman to work with my tanks primary ability. Sucks when they just stop casting cause something i hit caused the default bar to move up in wow.
2) I Use keyclone and have not for the life of me figured out how I press "Modifier+key" and make it correspond on another machine as say "g"
