This page presents a list of tutorials in video form with commentary to demonstrate how to best use the various capabilities of this web site.
You get to this dialog by from the top level page.
To view a tutorial simply click on the name of the tutorial. Although these are not actually hyperlinks to other parts of the site, they are decorated as if they were hyperlinks to remind you that you can click on them.
When you click on the name of the tutorial, the first word changes from "Show" to "Hide" and the video appears below the title ready to play. This is presented using the video player capability that is built into HTML5. Before clicking on the "Hide" link remember to stop the playback, as the "Hide" link merely hides the video player.
