What are the F1 through F12 keys?

The function keys or F-keys on a computer keyboard, labeled F1 through F12, are keys that have a special function defined by the operating system, or by a currently running program.


They may be combined with the Alt or Ctrl keys.


On laptop computers

On some smaller keyboards, including those on many laptop computers, the F-keys may have a dedicated function such as changing the brightness of the screen, the volume of the audio, or other device-specific functions.

On these keyboards, there is typically a separate Fn key that you can hold down to indicate that you want to use the key as a standard Function key.

For instance, on the MacBook Pro laptop computer, the F12 key's primary function is to increase the audio volume.

If this key is pressed while the Fn key is held down, the key will register as F12, and trigger any software functions that are configured to use this key.



If you would prefer not to press the Fn key to access your function keys, you can configure the keyboard to treat them as regular Function keys in your Control Panel or System Settings.

If your keyboard does not have a row of function keys, they are probably set up as secondary functions on other keys.

Look for alternate labels on your keys, or consult your computer's manual for more information.

Below is a listing of some of the more common functions of the functions keys for Microsoft Windows and Microsoft applications, as well as some for macOS.

As mentioned above, not all programs support these function keys, and the function keys on your keyboard may perform different tasks than those mentioned below.
