much better than 4 minute tutorials where you lose your train of thought changing videos. 30 minutes seems fast, but we can freeze it, study the code, and back up as much as necessary. so, for me, it was about an hour (about a typical college class length), because i watched it at my own pace.
typical poorly done clip. it shows picking from a list on the right, but doesn't show how to get that list to pop up.
