+The touch control scheme can be configured in the global settings. From the Launcher, go to **Options > Backend > Choose the preferred touch mode**.
+It's possible to configure the touch mode for three situations (ScummVM menus, 2D games and 3D games) and choose one of the three possible modes:
 
-    - When touchpad mouse mode is off (default), the touch controls are direct. The pointer jumps to where the finger touches the screen.
-    - When touchpad mouse mode is on, the touch controls are indirect. The finger can be far away from the pointer and still move it, like on a laptop touchpad.
+    - Direct mouse, the touch controls are direct. The pointer jumps to where the finger touches the screen (default for menus).
+    - Touchpad emulation, the touch controls are indirect. The finger can be far away from the pointer and still move it, like on a laptop touchpad.
+    - Gamepad emulation; the touch control don't move any mouse. The fingers must be placed on lower left and right of the screen and respectively emulate a directional pad and action buttons.
     - The pointer speed setting in the :doc:`Controls tab <../settings/control>` affects how far the pointer moves in response to a finger movement.
 
+The touch mode can be switched at anytime by tapping on the controller icon, next to the menu icon at the top right of the screen.
+
+To display or hide the small controller icon, from the Launcher select **Options** and then the **Backend** tab. Tick the **Show on-screen control** box to enable the keyboard icon.
