Adding AutoShapes, WordArt, and Hyperlinks
PowerPoint also allows you to add hyperlinks to your slides to make them more interactive. A hyperlink can link to a website, which provides more information for your presentation.
If this button does not show, you may want to add it to your toolbar by clicking the down-pointing arrow at the end of the bar to display Toolbar Options. Click Insert Hyperlink to add the button to your toolbar.
To make sure the hyperlink works, click the Slide Show button and click the link on the slide.
