You can turn text, images, and shapes into hyperlinks that perform any of several actions when you click them during a presentation. When you make an object into a hyperlink, it’s marked with a curved-arrow badge on the slide canvas; this badge isn’t visible when viewing the presentation. But text that’s been made into an inline hyperlink is underlined; the text underline is visible when viewing the presentation, unless you choose to reformat the text without it.
Use hyperlinks to trigger any of the following actions during your presentation:
Jump to a particular slide.
Open a webpage in the computer’s default web browser.
Open another Keynote document.
Open an email message.
Exit the slideshow.
