Accessing Dreamweaver's JavaScript API
Macromedia's Dreamweaver is one of the most popular visual HTML editing tools. And for good reason -- it's powerful, accessible, and it generates pretty good code. During Dreamweaver's evolution, Macromedia has added some interesting new features -- most notable for our purposes is the enhanced JavaScript functionality.

Not only the application is scriptable, it (almost) supports the DOM Level 1 spec and defines its own JavaScript-API with more than 400 different functions. It's also possible to customize the menus and incorporate new commands into it.
