Magic Keyboard with Numerical Keypad

Bingo!

When I set the keyboard preferences to Danish, then the comma and dot symbols can be used alternatively with the option key.

Problem solved. (Not sure why it has to be Danish, but that seems to be the one which works...)

Sorry for my typing error: The keyboard has the key configured (not misconfigured) to a . (dot) My problem is that I have no idea how to change this to the second option of a , (comma) as indicated as the symbol on the keystroke.

Thank you for the responses and Yes, the middle key of the bottom row of the keypad does have both characters on my keyboard. Judging by the responses I have received on my post, I believe this is not normally the case, so I will return to the Mac sales shop and get them to clarify this. It is odd as nowhere on the web documentation, the comma, dot key symbol is visible or described.

I am using English language , the keyboard is Netherlands version. However the plot thickens as today, I took the keyboard to the iMac premium seller shop and on their Macbook the two symbols can be used by pressing the option key with the symbol key. However that does still not work on my Mac. I'm still at a loss.

Yes, I did try and no effect at all. In fact I tried the combination with all possible keys, but unable to get the comma with this key.

I am using ABC extended, but do not know what they were using.
