A summary slide is a bulleted list of titles from selected slides in your presentation. You can create a summary slide to use as an agenda slide for a presentation. To create an agenda or summary slide, you select the slides that you want to include from Slide Sorter view, and then you click the Summary Slide button on the Slide Sorter toolbar. In front of the first selected slide, PowerPoint creates a new slide that has a bulleted list with titles from selected slides.
