Ctrl or Fn for Function Key

Jun 22, 2018
Fn key not working. How to toggle function lock?

You can use Fn + F1-F12 to control various ascpect of your computer, such as Fn + F1/F2/F3 to control volume or Fn + F10/F11 to control brightness.

Strangely, my notebook comes with Fn not working by default, where Ctrl key is used instead.

To enable Fn key, you need to enable Function lock (there is a Fn lock icon on my Esc key). Press Fn + Esc once to enable function lock (sadly, there is no visual indicator if fn lock is enabled or not). Now you can use Fn + F1-F12 to control your computer.
