I have a small aluminium usb french apple keyboard. A few of the keys do not match up but I have at least located them and written the correct symbols for these eys. However I have been unable to locate the 'at' symbol 'arobas' in French. Anyone help?

Does anyone know where the 'at' symbol ('arobas' in French) on the small aluminium usb french keyboard actually is? I have found most other symbols - not all are where they are meant to be. This keyboard is plugged into an HP British computer where I have changed the language settings to French.

It is printed on the second top left key but both upper and lower case here are actually the arrow symbols. As i mentioned not everything is where it should be. I would be grateful if anyone who knows would pass on this information.
