press.
In toggle mode, you turn the backlight on with a two-finger tap.
The backlight stays on until you tap with two fingers again.
By default, the backlight is in automatic mode. You can change the
backlight mode as well as the backlight brightness from the settings

NOTE: Backlight brightness affects battery life. The brighter the
backlight is, the quicker the battery drains.
