I would put it in "this workbook" of the Personal workbook, since it sounds
like you want to use it for all your Excel work.
I found the place to save the Personal workbook by running the following
macro:

Public Sub ShowPaths()

MsgBox Application.StartupPath

End Sub

Hi Jen,

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

pasted into your workbook's ThisWorkbook code module will disable the
F1 key.
