If you are part of the Office Insiders program, you will notice a new feature in PowerPoint 2016 for Windows. This new feature, named PowerPoint Zoom lets you easily create interactive, non-linear presentations with smooth hyperlinking between slides and sections. Plus, you can create slide thumbnails with hyperlinks on the fly!
Microsoft put up a video showcasing the PowerPoint Zoom feature, shown below.
You access the Zoom feature in the Insert tab of the Ribbon in the Links group (see figure below).
If you use Zoom on an older or unsupported version of PowerPoint, you will find that it has been substituted with a Dissolve transition effect.
