This just happened to me in WORD....I got this from the 'Office Assistant' help feature: go to Tools, then Customize, then Keyboard, then in the Save Changes box click current doc. name and then click on Reset All. It will restore all keyboard shortcuts to their original settings...however...I was not able to select 'restore all', so went to Tools/customize/options and clicked on 'reset my usage data', and that did the trick! Thanks for your responses....had I not happened upon my solution, I would have used yours...was previously in a huge bind!
