I'd like to point out that you can also "stack" macros so they're all layered on one position in the macro palette by making use of the follow syntax: /macro set #

This lets you jump around to different lines in your macro book, so you can have a setup that looks like this:

CTRL 1 (first line in macro book):
/equip stuff x5
/macro set 2
CTRL 1 (second line in macro book):
/equip stuff x5
/macro set 3
CTRL 1 (third line in macro book):
/equip stuff x5
/Ja MurderTown <t>

This lets you swap out a full 15 pieces of gear and execute your spell, Weaponskill or whatever with 3 keystrokes. If you run out of space in a single macro book you can switch between them using: /macro book #

Happy macro building.
