The FN (Function) key is an important part of any computer keyboard and the same goes for Mac keyboards. This key, when pressed in combination with other keys, can perform various functions such as adjusting the brightness of the screen, changing the volume, or even putting your Mac to sleep. It is a very useful tool that makes controlling your computer much easier.

So where is it located? On most Mac keyboards, you will find the FN key in the lower-left corner. It is usually located between the left Control key and the left Windows key making it the second key from the left on the bottom row of the keyboard. However, some Mac keyboards may have a different layout so make sure to check your particular model before using it.

You can use this key in conjunction with other keys to create shortcuts and perform various tasks such as changing volume levels or adjusting brightness settings quickly and easily. For example, if you press FN + F1 you will be able to decrease your brightness level while pressing FN + F2 will increase it. Similarly, pressing FN + F10 will mute audio while pressing FN + F11 will lower it, and pressing FN + F12 will raise it again.

The FN Key also works in conjunction with other keys to open certain applications or control media playback such as playing/pausing a song or video clip. For instance, by pressing Fn+F7 you can open iTunes while pressing Fn+F8 enables you to play/pause a song or video clip on iTunes or any other media player application installed on your Mac computer.

Overall, knowing where the FN Key is located and how to use it properly could save you time when controlling your Mac computer’s settings and performing tasks quickly and efficiently.
