Fn Button For Mac
Short for Function, Fn is a key found on most laptop keyboards and some desktop computer keyboards. The Fn key performs special functions, such as adjusting the screen's brightness and speaker volume.
These function keys are labeled F1 through F12/F19 (how many you have depends on your keyboard), along with an Escape key and an Eject key that looks like a triangle on top of a horizontal line. By default, every Mac has already assigned commands to the F8 through F12 function keys. By pressing and holding the Fn key in conjunction with another key that has an Fn function, that function is performed. For example, consider the photo above of the F12 key on an Apple keyboard. This key also has an icon of a speaker, making the F12 key an audio volume control key. Note: Changing system function key preferences affects how the function keys work for your Mac, not just Excel for Mac. After changing this setting, you can still perform the special features printed on a function key. Just press the FN key. For example, to use the F12 key to change your volume, you would press FN.

How do I use the Fn key?
With most computer keyboards, the Fn key is used like other modifier keys (e.g., the Shift key). By pressing and holding the Fn key in conjunction with another key that has an Fn function, that function is performed.
For example, consider the photo above of the F12 key on an Apple keyboard. This key also has an icon of a speaker, making the F12 key an audio volume control key. If you press this key, it adjusts the volume of your speakers. However, if you hold down the Fn key when you press the F12 key, it's interpreted as the F12 key. Holding down Fn changes from the default key action to the alternate. You can configure which action is the default, and which action is the alternate, in the keyboard section of your System Settings.
TipOn desktop computer keyboards with an Fn key that lights up when enabled, you need to make sure the key is enabled (illuminated) before pressing the corresponding function key. Once the key is illuminated, it no longer needs to be pressed, and each function is performed until the Fn key is disabled.
My Fn key does not have multiple colors
Not all Fn keys are color-coded. Computers with a white or black Fn key still perform the same function and can be pressed in combination with other keys that have pictures on them. For example, pressing the Fn key and a key with a sun on it should adjust the brightness. Pressing the Fn key and a key with a crescent moon should put the computer to sleep.
