Auto-Advance moves the viewer forward on its own. Actions let the viewer choose where to go. Together they are what make a presentation interactive instead of linear.
Auto-Advance #
Use it when a slide should move on by itself once it finishes, with no click from the viewer. This is what brings each section back to the Main Menu automatically so they can choose another topic to learn about.
- Click Slide in the left hand menu.
- Select Auto-Advance.
- Use the Next Slide dropdown to choose what plays next.
Actions #
Use them when the viewer should click a button or an image to choose their own path. This is what makes a Main Menu work: the viewer picks a section, watches it, then comes back to the menu to pick another.
- Click the button or image.
- Select Actions.
- Choose from the dropdown: go to a slide, open a link, toggle a selection, or finish the presentation.

What happens if you set neither #
A slide with no interaction defaults to auto-advance to the next slide on your timeline. So a presentation can be linear if you want it to be, it just does not have to be.
Setting an Action on a slide sets that slide's Auto-Advance to No/Off.
Tip: Name your slides before you start wiring up destinations. Picking "Pricing Menu" out of a dropdown is far easier than picking "Slide 14", and unnamed slides are the single most common reason a Main Menu button ends up pointing at the wrong place.
