Zoom areas help you draw the learner’s attention to important sections of a slide. For example, if you create a simulation that includes a step that might be easily overlooked, you can add a zoom area to highlight the step. After you add a zoom area, you can add timing, transition, and audio options to the zoom effect. Zoom areas consist of the following:
The area of the slide that you want to magnify.
Zoom destination area
The area in which the magnified portion of the slide is displayed.
