The improved Navigation Pane (formerly called the Document Map) gives you a visual representation of the headings in your document.
● Browse headings to quickly find your place within a document and just click to go to that location.
● Drag and drop headings to easily rearrange those headings and the content beneath them.
To open the Navigation Pane: On the View tab, in the Show group, select Navigation Pane. Find what you need, when you need it
The improved Find experience is now seamlessly integrated in the Navigation Pane. Word 2010 automatically searches as you type the term you need.
● Just start typing a search term in the search box at the top of the Navigation pane. The headings view in that pane highlights the areas in the document in which results appear, as you see here.
● The thumbnails view filters to show you just the set of pages that contain a search result.
● The new results view shows a quick preview of all search matches—click any preview to jump to that point in the document.
Tip: The familiar Find and Replace dialog box is still available for more advanced searches and Replace tasks. To access this dialog box, in the Navigation Pane, click the arrow that appears on the right side of the search box. Or, press Ctrl+H.
