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 some smaller keyboards and laptop computers the F-keys may have a dedicated function such as changing the brightness of the screen, the volume, or other device-specific functions.
On these keyboards, there is 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. Sort Posts by Likes.
