AutoSummarize is nifty little feature that summarizes your document by examining the content and selecting sentences that best relate to the main theme. Just click on Tools in the menu bar and then on AutoSummarize.

A window will appear with several options. There are four types of summaries you can choose from. These are 1) highlighting key points, 2) creating a new document with the new summary, 3) inserting an executive summary at the top of the document, and 4) hiding everything but the summary without leaving the original document. Just click on an icon that represents the option you want.

Designating the summary's length is another option. You can determine the Percent of original you want condensed. Once you choose a size in Percent of original, Word will tell you how many words and sentences from the original document will be summarized. These will vary depending upon the degree of summarization you choose.
