Trinity, as far as bar mods go, is relatively straightforward. You can use it straight out of the box, or set up additional bars by clicking on the little green circle next to your minimap (4 additional buttons pop out).

To save a template, right-click on the minimap icon. You can set your keybindings with the green key button, and edit spells/macros/items/abilities by using the white keyboard-looking button.

Another advantage of Trinity is the extended length for macros -- it allows for more characters than the in-game /macro system.


Minty is right, though. If you use /focus for your targeting, you can just /focus yourself and all the buttons will work. You'll have to re-bind the "wasd" keys if you have them unbound, though.
