unhide command h
I was typing in a word document and accidentally hit command+h while typing. The document disappeared and I haven't been able to retrieve it. I've tried reopening the document, and using a shortcut suggested on another forum (command+option+n) but nothing happens. I can open other documents in word. I haven't quit the application yet because I'm afraid of losing my unsaved changes. Any advice?
