On the function keys of a typical keyboard, there are two sets of actions. For example, the F8 key can have a secondary action of playing music. Most keyboards have a modifier key labeled Fn that can be used to execute both commands.
The Fn key functions as a shortcut, allowing you to perform a variety of actions quickly.

However, the Fn key can sometimes prevent the use of certain ‘F’ keys. You can lock the Fn key to prevent it from limiting the use of function keys. This will eliminate the need to hold down the Fn key when switching between actions.
