When I press the key left to the 1 key on the K6 Pro/ K8 Pro ANSI/US layout, I always get § and ±. How do I get "~" and "`"?

1. Please go to System Preferences > Keyboard > Change keyboard Type, and select ANSI.

2. Check if you selected British as the language input source.

 

 

3. Check to see if your device has installed other apps to remap the keys. They may interfere with the keyboard, such as Karabiner.
