IMPORTANT VIEWING NOTES
- Most slides have two or more animations or developments. Therefore, while you are in each slide (including the first blank white slide), click in the slide display area repeatedly with your mouse until all sound and animation is complete. Only then, select the next slide by using the navigation arrows at the bottom of the slide display area.
- For your convenience, the slide list/outline at the left side of the screen presentation can be used to jump directly to any desired slide for review. You can also expand (or collapse) the slide list/outline to show more detail. Just click the rectangular button at the bottom of the slide list/outline.
- The vertical separating bar between the list/outline and the slides may be dragged left or right to change the relative sizes of the two parts of the screen.
