keyboard keys

[Sparky]

1-9 work when I press them. 0 displays a multiplication symbol star when pressed which is the symbol if Fn was pressed. F1-F12 work fine as well as their Fn characters. What is causing 1 key when pressed to display the Fn character of that key?

Fixed it by pressing the NumLk.

If it's just one key, then I think that one key has gone bad.
