How to change the function of the Fn key on Windows 10 and 11

The function keys at the top of the keyboard act as shortcuts to control certain hardware features. For example, if you want to turn on the backlit keyboard, they allow you to do so with a single key press without having to do the same through Windows.

By default, these keys can only be used when you press the dedicated Fn key along with them. However, you can customize this setting, along with many others, to suit your needs. Here are the different ways you can modify the settings for your Windows 10 and 11 function keys.

1. How to change Fn key settings using Windows Mobility Center on Dell computers

How to enable Fn lock

If you don't want to press the Fn key every time you want to enable/disable any of the 12 functions, you can turn on Fn lock. With this feature, the Fn key will always be held on the keyboard and you will be able to use any function key without having to press the Fn key first.

On most keyboards, Fn lock is mapped to the Esc key, but your device may be different. Typically, these keys have a lock icon on them. You can use the manufacturer's website to find it on your device if you can't find a key with a lock icon.

Once you find it, hold the Fn key and press the lock key to enable the feature. You can follow the same steps to disable it in the future.

Function keys are great for improving productivity and efficiency. With the right techniques, you can get the most out of them. Hopefully, following the steps above will allow you to modify the function key settings to suit your needs. It is also important to note that none of the methods outlined above will make permanent changes to your system, so you can always revert the changes if you want.
