This has happened so many times where I would get done with my presentation at a conference and someone would come up to me and ask: "How were you drawing on the screen so fluidly? What tool do you use?"
Well, after hearing that question a few dozen times, I decided I needed to create a video to quickly show how I use the ZoomIt tool to make my presentations much more engaging then just static pictures. The following short video shows you exactly where to get it and how it's used. I hope it's helpful to my fellow presenters out there.
ZoomIt tool - screen annotation and zooming
I personally have gotten a lot of mileage out of this tool over the years. The more I used it, the easier it got for me.
I hope it can be helpful to you as well. Enjoy!
