Access Controller configurator. Use the Left and Right arrow keys to move between sections, Up and Down to move between options, and Left or Right to change a value. Press Enter to confirm and Escape or Backspace to go back. Press the question-mark key for the full list of controls. You can also use the Access Controller itself: the stick navigates, the center or stick-click confirms, and any ring button goes back.
The controller is only observed here — menu navigation pauses so you can press every button and fully move the stick without scrolling the bar.
Open this in Chrome or Edge (desktop) to use the XMB configurator.
