Add buttons to go forward and back.
1. Open your basic PowerPoint presentation
by double-clicking on your presentation's icon.
2. Select View --> Master --> Slide Master.
Anything you do to this "slide master" will appear on all of your slides; we're going to put the buttons here so that we don't have to do them for every single slide.
3. Click on Insert--> Action Buttons --> Back or Previous.
4. Click and drag to make a button on the lower left.
5. Make sure that the "hyperlink to" says "previous slide," then click OK.
6. Make a "next slide" button in the same way: Insert --> Action Buttons --> Forward or Next.
Make the "next slide" button in the lower-right corner of the screen.
7. Select View --> Normal to go back to the normal view:
8. Try out your buttons by clicking on Slide Show --> Play from Start.
You may want to move your pictures and text out of the way of your buttons.
9. Save your presentation.
