I am abysmal at classic macros , all the interesting scripts and lua modification you can do is so beyond me it isn ' t even funny , but I ' m sure there is some information on 1 . 12 . 1 Forums that could maybe help . I mainly use it because I like having the extra space and it just being a generally cleaning look and easier to navigate . One such example of SuperMacro Sorcery script if IsShiftKeyDown then CastSpellByNameFaerie Fire FeralRank X else CastSpellByNameGrowl endShift to cast Faerie Fire and no modifier to cast GrowlEDIT Here ' s a to a question someone else asked about SuperMacro . Reading through it made things only more confusing for me , being the dumbass that I am , but someone with some scripting knowledge would find it helpful . EDIT EDIT After rereading those lines of code over and over it seems that the macro in the picture is just to only cast rejuvenation on a target if they don ' t already have an active application of it , unless you hold down shift which forces the script to reapply rejuvenation regardless of it being active on the target or not .
