The Action Bar is the left-most part of the Interface Bar at the bottom of the screen, and is used as a ready source for command shortcuts (abilities and spells). Player may drag and drop icons into the Action Bar in order to create a customized interface

The advantages are that I only have to bind the main action bar, and can hide the extra bars and keep my screen uncluttered. Also, I never have to use modifiers. The two-key sequence I press for many moves, if it is slower, seems to be irrelevantly so.
