Backstage

This obviously delights a Drama teacher.

In Office 2013 the ribbon holds all the commands to work on your file.
But when you want to work with the file - you now have to go backstage - well, that's what Microsoft calls the behind-the-scenes area. It lets you print, open, save, share etc etc.

You get to the backstage are by selecting the FILE tab.

When you click this (or Alt F if you like keyboard short cuts) the file you are working on temporarily disappears and the screen looks something like this.

Click any of the left side options to do different things.

To go back to your document? Simply click on the arrow top left.
