Dreamweaver Extensions
Dreamweaver was written for professional developers and, in order to satisfy the needs of professionals, Dreamweaver is extensible. The entire menu system is customizable, you can add keyboard shortcuts, you can create commands using HTML and JavaScript, and you can create custom tags, panels, toolbars, and objects.
In addition to creating your own extensions for Dreamweaver, other developers have developed extensions and they make them available to the Dreamweaver community. Many extensions are available at no cost, but there are also commercial extensions. One of the best sources for Dreamweaver extensions is the Macromedia Exchange.
While there are hundreds of extensions available through the Macromedia Exchange, there are many other sites that offer extensions, both free and commercial. You can do a Web search for Dreamweaver extensions.
Some Recommended Extensions
Here are some of the Dreamweaver Extensions that we use and recommend:
Lorem and More...
When building new websites, most designers use a piece of filler text that's been known to printers since the 16th century — Lorem ipsum — or perhaps some random corporate mumbo-jumbo. Lorem and more offers you the choice of traditional Lorem ipsum, a bit of genuine Cicero, random corporate nonsense, and for romantics — Sonnet 116 by Shakespeare. It also offers a choice of format — paragraphs, continuous text, ordered and unordered lists, and in the case of Shakespeare, formally laid out as a sonnnet.

Smart Link
Smart Link converts an existing link so that the target page opens in a new browser window. It works in a similar way to the Dreamweaver Open Browser Window behavior, or using target="_blank", but gives you far more control over its look and position. Although it uses JavaScript, it is smart enough to work even if JavaScript is disabled (by opening the page in the same window) — keeping your site accessible to everyone, and far more user-friendly than a link that doesn't work at all. It also has the advantage of keeping your pages valid, unlike target="_blank" which has been deprecated by the W3C.
