Playing on ps3 and still trying out some bar macros and ran into this one. To help with fast bar changes for abilities I don't use often.
/chotbar change #
Just started using it but here is an example for my pet heal and then back to my main bar in one button.
/ac "sustain" <pet>
/chotbar change 1

More uses for /chotbar command I found at the bottom of this page. http://ffxiv.consolegameswiki.com/wiki/Commands
