Mastering the UI / Cross Hotbar
The cross hotbar can be used by holding either LT or RT (L2 or R2 on PS5™/PS4™, LT or RT on Xbox Series X|S) and the corresponding directional or action button. But first, you will need to register actions to the cross hotbar, as described below.
From the main menu, select Character and open the Actions & Traits menu. From the tabs on the left you can peruse several categories containing various actions to register to your cross hotbar.
In addition to actions, you can also register items, mounts, minions, and emotes.
When you've found an action you wish to register to the hotbar, click and drag its icon to your desired cross hotbar slot.
With the Hotbar Palette open, press the button combination you wish to assign your selected action to.
Once registered to your cross hotbar, actions can be used at any time via their corresponding button combinations.
