Can't help, item was returned.

Hi Linda.
I'm in the office right now and don't have the device handy. But I had the same question once and I think it's like on the "normal" keyboards. Say: ALT-GR 2.

The @ sign is not printed on the Targus keyboard, but the key assignment is still the same as on the big ones. It is also important that you have set the input language to German (Switzerland).
