Ways to highlight during a presentation
Solution 1:
Mouseposé
When turned on, it dims the screen and puts a spotlight on the area around the mouse pointer, easily guiding the audience‘s attention to an area of interest.
Additionally, it has the mouse click visualization and typing visualization - both allowing your audience to see what you click and type.
They have a video on their site that shows the software in action.
Ink2Go
Ink2Go is an extremely simple and powerful screen annotation and recording software. Using Ink2Go you can easily write on top of any other application currently active on the desktop, even on a running video.
There is a 15 day free trail available at their website. They have both Windows and Mac versions. In addition, there is a number of YouTube videos showing the product in action
This one may be a bit of overkill given all the features, but I have seen this at work in an education setting and it's excellent software.
Solution 2:
For Keynote presentations, by using an iOS device as a remote one can draw or use a ‘laser’ pointer on the slides. Although not as elegant as drawing focus to an element, it certainly grabs attention.

Solution 3:
Logitech Spotlight Presentation Remote
Apple says:
With Spotlight you can take a giant step beyond traditional laser pointing. This advanced system lets you precisely highlight or magnify areas of focus in pixel-perfect detail. It's clearly visible to both the audience in the room and everyone watching via video conference.
