When you have numerous Microsoft Word documents open at one time, it isn't necessary to save and close each document individually before exiting Word. You can save all of the Word documents at once by pressing [Shift] and then going to File | Save All. Word will save all of the changes you made to the open documents at once. The Save As dialog box will display for any files that have not already been named.
You can close multiple documents in one fell swoop by pressing [Shift] and then going to File | Close All. If any of your documents contain unsaved changes, Word will ask you whether you want to save your changes before closing the particular file.
