Creating a table of contents in PowerPoint is one way to summarize your slideshow and move to certain slides easily. But another way that makes your presentation more dynamic is using a Summary Zoom slide.
A Summary Zoom in Microsoft PowerPoint is a slide containing thumbnails of slides or sections in your presentation. When you select a thumbnail, the zoom transition appears and then takes you to that slide or section. This is a fabulous way to enhance your presentation, especially a lengthy one or one using sections.
Note: As of March 2022, you can create a Summary Zoom on Windows with Microsoft 365 and in PowerPoint 2019. For Mac and mobile PowerPoint users, you can play a Summary Zoom, but not create one.
Create a Summary Zoom in PowerPoint
If you already have sections in your PowerPoint slideshow, those sections will be used for your Summary Zoom. If you do not have sections, PowerPoint makes them for you when you create the Summary Zoom.

Open PowerPoint to the presentation you want to use and go to the Insert tab. In the Links section of the ribbon, click the Zoom drop-down arrow and pick “Summary Zoom.”
When the Insert Summary Zoom window opens, choose the slides to include and click “Insert.” Each slide you pick creates the beginning of a section. This allows you to select a slide, move through its section, and then return to the summary slide.
You’ll then see the summary slide with your thumbnails and a spot for a title at the top. Click the title box to insert your text or select it and press Delete to remove the title box.
You can also see the sections that are used in Normal or Slide Sorter view. By default, the name of the first slide in a section is the section name. To change this, right-click a section and choose “Rename Section.”
Keep in mind that the Summary Zoom is the first slide in your presentation in its own section labeled Summary Section.
Customize a Summary Zoom Slide
A Summary Zoom slide includes a few default settings that you can change if you like. Select the zoom section on the summary slide. Then, go to the Zoom tab that displays.
