back to front keys on keyboard

H

helpme

Somebody PLEASE help. I was pressing Ctrl, Alt and 4 to retrieve the euro sign, and must of accidentally pressed another combination of keys, as now the euro sign does not work, and if i try to get the @ sign, i get the " symbol, and so on.
This is a large spreadsheet, and it is not practical for me to redo it on another workbook. It is only on this workbook at the moment, but on every worksheet throughout.
Does anybody out there know how to revert back to the original keyboard settings???
