The outline format helps you edit your presentation's content and move bullet points or slides around. When you write using the Outline tab, buttons become available on the Standard and Formatting toolbars that let you increase or decrease text indents, collapse and expand content so that you see slide titles but no subordinate bullet points, and show or hide text formatting as you work.
The content in your outline can come from many sources: you can type it in originally; use prepared text provided by the AutoContent wizard; or insert text that has heading and subheading styles and is in another file format, such as .txt or .doc, from Microsoft Word.
When you save your presentation as a Web page, the text on the Outline tab becomes a table of contents so that you can navigate through the slides.
