This user interface element allows you to place anything you use, including items, spells, skills, weapons, and party commands, on a bar that goes across the bottom screen. By pressing the number keys or hyphen (-) and equal (=) signs, you can quickly use any of these actions.
Pressing the square brackets ([, ]) allow you to cycle through all your quick bars. You can also press shift and a number key to access the corresponding quickbar.
You can have 10 quick bars total, each with 12 actions.
