Outline view provides a powerful way for you to view the structure of your document and to rearrange the order of presentation of the topics. The outline structure assumes that you’ve used specific heading and body styles to organize your document into a hierarchy of topics and subtopics.
Click the Outline View button at the bottom-right of your screen to switch to Outline view.
On the Outlining tab, specify the lowest level of heading to be displayed.
Click to expand or collapse the content under the selected heading.
Click to change the outline level of the selected text by promoting it one level or demoting it one level, or to change body text to a heading or a heading to body text.
To move a section, click the plus sign to select the entire section, and drag the section up or down.
