How to lock Fn if you have one on your keyboard

You will notice a small padlock icon on the Esc key if that is the case for your keyboard. To lock the Fn key, simply press the Fn key and the Esc key together. Once the lock icon lights up, the Fn key has been successfully locked. To unlock, you can press both keys together again.

When it is locked, you don't have to press Fn together to get F5 or something else like that. Enjoy!
