Lock keys into function mode
If you’re using an app that uses function keys a lot, you can lock the top row of keys temporarily
so the function keys stick.
When the function keys are locked, pressing a key on the top row gives you the function key
(like F3 instead of ). Pressing Fn plus the key gives you the special key. For example, to mute the
speaker, press Fn+ .
To lock and unlock the Fn keys:
 Type Cover, Type Cover 2, and Type Cover for Surface Pro 3
Hold down the Fn key and press the Caps key to lock the function keys. Press Fn+Caps
again to unlock them.
 Surface 3 Type Cover, Type Cover for Surface Pro 4, and Surface Pro Signature
Type Cover
Press the Fn key to lock the function keys. Press the Fn key again to unlock them.
A light appears on the Fn key when you’ve locked the keys into function mode.
Add an input language to your Surface
Surface Covers are available for a number of languages and alphabets. If your Cover has a key
marked Alt Gr, you can use it as you would Ctrl+Alt.
You can also set up your Surface to use other languages and keyboard layouts. See How to add
an input language to your PC and How to switch input languages in Windows to learn more.
These settings stay with your Surface and apply to any Cover you attach. If you use your Cover
on another Surface, the input language settings for that Surface will apply.
