Mastering the UI / Player Actions
Actions can be made readily available for use at any time by setting them to a hotbar or cross hotbar.
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 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 hotbar slot.
Once registered to your hotbar, actions can be used at any time via their corresponding shortcut commands.
