Previewing is an easy way to see how a presentation looks to users. If you want to check your work, preview presentations at any time using the Preview options in the Presentation group.
When you preview a presentation, it appears in your default web browser. All of the functionality in the presentation, such as audio and quizzes, works exactly the way it will in the Adobe Presenter viewer. The presentation appears with all of the theme settings and colors you have chosen.
You cannot preview attachments.
In PowerPoint, open a presentation (PPT or PPTX file).
Click Adobe Presenter, and in the Presentation group, click Preview and choose one of the following options:
To preview the entire presentation.
Preview Current Slide
To preview only the currently selected slide in the presentation.
Preview From Current Slide
To preview the presentation starting from the currently selected slide.
Preview Next 5 Slides
To preview the next five slides starting from the currently selected slide.
You can change the value 5 to any other required value in the application settings (Adobe Presenter > Tools group > Settings > Application > Preview).
To preview the output as HTML5 in browser.
