Making Dreamweaver behave

For some reason, I've had a mental block for a while now about using Dreamweaver behaviors. For the longest time, I thought they required some type of server back-end like PHP or a database to use. So I never even tried. Then when I finally set up PHP and a database on my server I was surprised to discover that most behaviors are just JavaScript. And Andrew Whiteman does a nice job explaining how to add Dreamweaver behaviors so now I have no excuse. And since there are so many pre-installed Dreamweaver behaviors there is bound to be one that will be useful. For instance the validate forms behavior, or maybe the swap image behavior.
