Here is the link to my screencast. http://screenr.com/Yqgs
I chose to use "screenr" mainly because I liked their instruction video better. It took several tries to get it right but that was only because I got tongue tied and couldn't spit the words out right.
I think that this could be a useful tool. It is easy to create and share. I had no idea that this sort of thing was available and look forward to finding ways to use it.
