A slide show portlet facilitates a slide-based presentation. You select a set of slides from the Portal Media document library located at:
DI\Solution\webdata\<diveport>\doc-libraries\Portal Media\slides
The slide show displays on a web browser.
NOTE: The slide show portlet requires a separate license.
The slide presentation has a page selector that you can use for navigation. 
Example
If the slide show portlet is presented as a pop-up click action, use the following keys for navigation:
- Next slide—Press the Right arrow, Enter, or Page Down key
- Previous slide—Press the Left arrow, Backspace, or Page Up key
- Close—Press the Esc key
