Can't make function keys work on Anker Ultra-Slim Bluetooth keyboard


Here is a picture of the keyboard

I have had this device for a long without using it but now it would be very useful. The only problem I am having is that I can’t make the Function keys work. For example, pressing F12 will increase volume. But no combination of pressing Fn with F12 will make it ever send F12. Instead it just always works as increase volume button.

The manual doesn’t give any hints.

Does anybody know how to make this work?

Have you only tried the function key with f12? Typically f12 is used as a save function in Microsoft office. The only other time it’s typically used is when starting a computer to boot into a specific boot drive. What is it you are trying to do?


It probably not the solution but I did have a keyboard once that had me press the shift key and the f12 to make the f12 key work so just an idea not sure if it’s the actual solution though

Sorry for writing “F12” Actually F11 was for volume. This didn’t work. F5 (browser refresh) also doesn’t work.

There is a tool where you can check the keyboard layout. and change it,
even the functions of the f-keys.
Normally f11 is for altering the browser to full screen as far I know.
