How do I zoom into a slide in a VoiceThread?
If you hover your mouse over any slide (except videos), a magnifying glass with a plus sign in it will appear. Clicking when this icon is present will zoom in on that section of the current slide. When zoomed in, you can also move your mouse around to other portions of the slide to view other areas. While you're zoomed in, the magnifying glass icon will have a minus sign within it, and clicking this will zoom the slide back out to full view.
