To display one bullet point at a time

1. Create a slide.
2. Add the first bullet point.
3. Select the entire slide and choose Copy from the Edit menu.
4. Choose Paste from the Edit menu.

   The slide is duplicated.

5. On the copy, add the next bullet point.
6. Repeat steps 3 - 5 until all of your bullet points are shown on a slide.
7. Time your media to show the appropriate slide at the appropriate time.

Displaying bullet points one at a time allows you to focus the viewers attention on the current point.
