Found under: Settings > Controls > Hot zones
Actions can be assigned to three hot zones on the Performance mode screen. The actions available are identical to those available for foot pedal or screen gestures and can be set for short press/click or long press actions.
The top left hot zone will move if an inline set is also visible. Hot zones, when assigned actions, will block normal screen interactions (scroll, zoom, custom screen gestures, previous/next buttons) when clicking on these areas.
By default, hot zones are switched off to avoid any potential conflicts with other screen interactions and gesture navigation on your device.
