The fullscreen Player occupies the entire screen and does not, by default, display any Player controls. You can access the Player controls by displaying the Player options from within the fullscreen Player (go through the south gate). The Player controls appear at the bottom of the Player options. You use them as you would in the Player view—see Using the Player Controls.
You can also use the Player hotkeys to navigate frames, set in and out marks, set a region of interest, and so on—see Player.
