When you are trying to play a video or audio file on your Mac, you might be able to find yourself using the f key. This is a great shortcut to use to jump to the top or bottom of the screen. However, you can also adjust the default behavior of the f key to enable or disable a variety of functions, including the ability to dim the screen or play the next track.

Dim the screen

The F-keys are the key to controlling screen brightness on your Mac. Besides the obvious use of F1, the keys can also be used to perform other useful actions. For instance, you can use them to open up an application.

The F-keys are located at the top of the keyboard. Some apps will assign these keys to functions that you might not be familiar with.

For example, F3 opens Mission Control, while F2 increases the brightness of your display. You can also use them to open up an app, or change tracks in iTunes.

If you have a desktop computer, the F15 key is a common way to control the brightness of your screen. It is also used to change contrast.
