How to activate Fn lock

If you don't want to press the Fn key every time you want to turn on/off 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.

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

Once you've found it, hold down the Fn key and press the lock key to activate the function. 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 settings of the function keys to suit your needs. It's also important to note that all of the methods outlined above do not make permanent changes to the system, so you can always revert the changes if you want.
