Word 2013 and 2016 automatically bookmark the page you were last on when you closed a document, and lets you return to that page when you reopen the document. Say you have a 20 page document and you were editing some info on page 12 and then decided to close the document. The next time you open that document a message box will appear that says “Welcome back. Pick up where you left off?”. You click on the message and you are immediately back at page 12. Very handy don’t you think?
