Hyperlinks in PowerPoint work the same way that they work on websites. A link can point to another slide in the presentation, an email address, a file or an external website. If you've created a link to a website in your presentation, make sure your computer is connected to the Internet before you try to open it. Make hyperlinks with the Hyperlink button when you create the presentation.
Open a PowerPoint presentation with hyperlinks in it.
