I have now found out myself. Download the Dell Universal Receiver Control Panel. Start the control panel. The instructions appear. Switch off the new device, keep the button pressed and switch it on. After approx. 3 seconds the message appears that the new device has been recognised. Confirm and you are done.
No, unfortunately that does not work. These keys also both fulfil the same functions (see link). I am very satisfied with the keyboard, although I would rate the keyboard as the better product of this 2-key combination.

Thanks, but I want to know whether I can use the keyboard with Mac OS (not via Mac with Windows OS) for a Mac user? Thanks again for your correct reply.
This depends primarily on the country setting of the keyboard on the laptop itself. If you can set DE-CH there, it will also work with the keyboard, even with the internal one if I'm not mistaken. The question is rather whether this can be easily changed in your settings.
