Another unique feature of Powerpoint presentations is that you can include animation effects as you change from one slide to another.

The animation effects toolbar can be accessed by clicking on the STAR tool as you can see here.

What pops up immediately is the full Animation Effects toolbar.

Each tool adds a different effect to the selected screen element. In PowerPoint (ie not on the graphic above!), try holding your mouse pointer over each tool to get an idea of what it does.

Then experiment.
