How to Draw an Action Button Hyperlink on Your PowerPoint 2007 Slide
On the Hyperlink To drop-down list, choose the action you want for the button.
You can go to the next slide, the previous slide, the first or last slide in a presentation, the last slide you viewed, or a specific slide. To make clicking the action button take users to a specific slide, choose Slide on the list. You see the Hyperlink to Slide dialog box, which lists each slide in your presentation. Select a slide and click OK.
