In case anyone doesnt know about this I thought I'd share with you all.

You know those abilities you need on the fly but not necessarily all the time so you don't want to have them up on your main crossbar. For example monks meditation, tornado kick. Warriors defiance and deliverance.

You can simply tie them to L3 and R3 (push button) using a macro.

Step 1. Map the controller buttons to macro
System Configuration>controller settings>controller customization
L3=execute macro #98
R3= execute macro #99

Step 2. Create the macros
Using the examples above for monk and warrior, which are the only ones I use. These are my current macros

#98 L3
_______________
/ac "tornado kick"
/ac "defiance"

#99 R3
______________
/ac "meditation"
/ac "deliverance"

Each different class I use static placed hotbars to show the cooldowns for each ability. I imagine if you have more abitilities to add you can just keep going down the list.
