Zoom in to Show Your Presentation Details

Ever seen a presentation where the presenter zoomed in to a part of the screen to show some hard to read details?

I always thought that it was a windows feature but I finally found it. This cool trick could be done with a product from Microsoft called ZoomIt.  It is hard to show an example of it, but  this is what my full screen looks like before and after zooming in.

I wish I knew about this before I used ctl + and - on my presentation. Enjoy!
