Chapter 2.3.3 Brightness
========================
Brightness is a tool to control your screen brightness. If you are using a laptop turning down your screen brighness can increase battery life by a large amount as well however too dim and the screen will be illegible.
Useage
------
To use brightness click on the dial towards the right window of the window. To make the screen dimmer use the :kbd:`left arrow` key or click on the dial and drag it towards the left. If you want to make the screen more bright press the :kbd:`right arrow` key or drag the dial towards the right. After doing this you will be asked to confirm the current brightness is ok while needing to select :guilabel:`yes`. If you do not respond it will go back to the old brightness which is useful because if you made your screen illegible it will revert to the old settings.
