The touch screen functions are some predefined special functions for i.e. display on/off, Go to page etc. on the touch panels equipped with a display.
The 'display' function can force a display to go OFF while bypassing the display sleep timer. Or it can switch the display ON.
The 'go to page' function will switch the page to the desired one. This function is only available on the AURUS-OLED (PLUS).
