Disabling Keys in Excel

Some one asked if there is a way to disable the F1 or any other key in Excel. 

The only way to disable a key such as this is to create a macro. The following macro will do the trick quite nicely to disable the F1 key:

Private Sub Workbook_Open()
    Application.OnKey "{F1}", ""
End Sub

Private Sub Workbook_BeforeClose(CANCEL As Boolean)
    Application.OnKey "{F1}"
End Sub

Actually, there are two macros here. The first one executes whenever the workbook is opened, and the second is executed when the workbook is closed. In the case of the first macro, the OnKey method traps every keypress of F1and cancels it. The macro that runs when the workbook closes restores the normal operation of the F1 key.

These macros can be placed in a given workbook, in which case they will only apply while that workbook is open. If you want them to apply at all times when using Excel, store the macros in the Personal workbook.

You can replace the {F1} with any key of your choice.
