Turning off Date AutoComplete in Word 2007

*..As it turns out, there actually is a way to turn this off in Word 2007, the statement to the contrary in that article notwithstanding. If you run the following macro, date AutoComplete should no longer occur:
Sub TurnOffAutoComplete()
Application.DisplayAutoCompleteTips = False
End Sub
Or, if you prefer a toggle, replace False with Not(Application.DisplayAutoCompleteTips).*
