I have just purchased a Microsoft Comfort Curve keyboard 2000. Less than a tenner in Morrisons. I have a dollar sign above 4, with theeuro symbol next to the 4 - so that shouldmean AltGr should do it. It sys on the box that it is compatible with windows 7 and Mac.It says too, that " box this box contains enhanced U K English105 key layout". Does this make the U. S. layout inferior? The main picture shows what I take to be a non U K layout (American?) It looks identical tome, but for the euro, and words too small to decipher on u i a f and x keys. I'm curious to know what they do.
