I have zillions of macros, a few other people might find useful;
druid travel forms / mount macro all in one handy little button :P (change the name of the ground mount to whichever you have)
/use [swimming]Aquatic Form
/use [flyable,nocombat]Flight Form
/stopmacro [flying]
/use [outdoors,nocombat]Reins of the Cobalt War Talbuk
/use [outdoors]!Travel Form
/script UIErrorFrame:Clear()
----
focus target/assist focus macro (for no brains dps'ing), alt-click to set focus, and then click again to assist focus
/focus target [modifier]
/stopmacro [modifier]
/assist focus
---
whisper focus macro (set focus with alt-click and then send message with normal click), can change the whisper message to anything, eg 'misdirect on you' or whatever and then combine it with a /cast[focus] line
/focus target [modifier]
/stopmacro [modifier]
/script if UnitExists("focus") then SendChatMessage("+++TAUNT+++","WHISPER",nil,UnitName("focus"))end
---
mark target with skull (for on the fly marking while tanking, change the number if you want a different mark)
/script SetRaidTargetIcon("target", 8);
---
show/use trinkets on action bars, useful if you have a zillion trinkets for different specs, this shows what you have currently equipped (yeah you can get mods that do the same but this is no extra memory)
#showtooltip 13
/use 13
and
#showtooltip 14
/use 14
