I bought this keyboard a long time ago. I am not happy with this device. Once the connection doesn't work, then it works and so on.
The keyboard is in the drawer waiting to be recycled. Sorry
It depends on what you have set on your PC (Windows settings -> Time and language -> Language, Apple I don't know). If it says German (Switzerland), it is the following key combination:
Alt (right of spacebar) + 2
