My powerbook G4 has somehow got the keys for the bracket symbols (these things above the numbers) on the 8 and 9 buttons instead of on the 9 and 0 buttons. Also there is no * printed above the 8. Anything I can do about this? All other keys are correct... including the £. Can I change the wrong keys? If so, how? (this is a repost owing to typos by me).
