The keyboard that I got with my iMac is Dutch and so the [.]dot and the [,]comma are changed on the right side of the keyboard(where all the numbers are, below the volume and eject buttons. So basically what I mean is that when I press the [.] button it gives me a [,] and I don't want that ...example: $25.95 is changed to $25,95 How can change it to it's original function without changing all the other buttons??
