Microsoft revamped its document map as the Navigation Pane in Word 2010. The Navigation view is shown here in a document that uses the built-in heading styles. It combines the map, an expanded search or find feature, and a page display in the one pane.

One way to see the Navigation Pane is to check the box on the View Tab. Another is to use the keyboard shortcut Ctrl+F (find).

The key to using the Navigation Pane to reorganize a document is to use the built-in heading styles to organize it to start with. See Moving/Reorganizing Pages in Microsoft Word.

See also: Outlining in Microsoft Word. The Outline view works in all versions of Word, at least since Word 97.

I had planned on writing a page on using the Navigation Pane because I think it is an underused feature. It appears that a number of other writers have beat me to it. I don't think I can add much. Here is the Microsoft Support Page on it.

Here, though, is a note about controlling its size and display at startup: Navigation Pane Settings at Word Startup. 

It is common to have Headings applied to something other than a whole paragraph not show up in the Navigation Pane. This is because they have been applied as "Linked Styles." Here is a link to my article on this: Headings that do not show up in the Navigation Pane or in a Table of Contents.

Beginning with Word 2013, the icons on the tabs in the Navigation Pane were replaced with words. Here is the Navigation Pane in Word 2016:

General look without going into depth on the three different functions of the Navigation Pane - Find/Search, Document Map, Page View. Ads are a little distracting.
