Some useful macros I stuck up on my blog that I thought you guys would find handy.

/run for i = 1, GetNumTrackingTypes() do local name, _, active = GetTrackingInfo(i) if name == "Track Humanoids" then return SetTracking(i, active == nil) end end

This turns tracking humanoids on and off with one button avoiding the drop down menu. You can change the name to be other tracking types.

/cast call pet #

This calls the pet #, like /cast call pet 1 will call the top pet in your pet summon list. It can be handy with vehicles or someone kiting your pet out of range in pvp.
