For some months, Word 2007 has been annoying me by automatically expanding the year to include the date if I type it at the end of a headline and then hit Enter. In Microsoft's view, this is convenient; in my view, it's a total nuisance. Unfortunately, while you can customise your own AutoCorrect and AutoFormat entries in Word 2007, you can't switch this feature off directly.
However, a handy post at the Word 2007 Bible Blog (itself no longer there, but handily preserved by the Internet Wayback Machine explains how to get rid of it. Here's the main steps.
If you haven't already got Developer mode enabled in Word 2007, switch it on by clicking on the Office button, selecting Word Options at the bottom of menu, and ensuring 'Show Developer mode in the Ribbon' is ticked.
Click on the Developer tab.
Click on the Visual Basic button.
Copy the following text and paste it into the bottom of the text that appears. (Don't overwrite any existing text, as this may affect macros you've already developed).
Sub TurnOffAutoComplete() Application.DisplayAutoCompleteTips = False End Sub
Select File —> Close and return to Microsoft Word to save the changes.
Click on Macros in the ribbon.
Click on TurnOffAutoComplete, and then click on Run.
That's all — date autocomplete should now be disabled.
