How to Change Key Function of Fn Key in Windows 10 and 11

Function keys, also known as "Fn" keys, are those keys on your keyboard that can trigger various functions of the F keys, located at the top of your keyboard. They're called shortcut keys since they're useful for basic but important functions like changing the volume, screen brightness, and backlight on your computer.

Most laptops have 12 function keys, though older devices used to have more. To use these keys, you need to press them along with the Fn key on your keyboard. For instance, if you want to turn on the backlit keyboard using the F3 key, you can press the Fn key first, then F3 to make the change.

By default, these function keys only work when you press them with the Fn key. But you can customize your settings and make changes that suit your preferences. For example, you can change your laptop's settings so that you can use function keys without pressing the Fn key every time.
