You can add transitions that occur between your slides. As your show moves from slide to slide you have an animated transition between them. It is a nice effect to add to your show. It is easiest if you add your transitions while in the slide sorter view. You can add the same transition to each slide or you can pick different transitions. To add transitions follow these steps: Get in the slide sorter view. Click on the Slide Transition button from the slide sorter toolbar. The slide transition dialog box will open. Click on the down arrow and choose the type of transition you want to use. You will see a little preview in the effect window. Choose if you want the transition to be slow, medium, or fast. If you want a sound attributed to the transition then click on the down arrow next to sound and choose the sound you want to use. If you want your transition to run when you click the mouse then put a check in "On mouse click". If you want the animation to occur automatically put a check in that box and put a number for the amount of seconds you want to wait until the transition occurs. Click on Apply to All if you want that same transition to occur after each slide or Apply if you just want to add it to the one slide.
