Using one macros for two different gear changes. For example:

/equip body "Haubergeon"
/equip body "Earth doublet"
/equip ring1 "Unyeilding ring"
/equip ring1 "Smiloden Ring +1"

Let's say you have Haubergeon and Unyeilding ring equiped, by using all of the above commands in one macro you can swap these to Earth doublet and Smiloden Ring +1. Then once you realised you made this terrible mistake, you can swap them back again using the same macro.
