Even though there is a reference tab in the Code Panel, the Tag Inspector Panel is even more useful. This panel shows you how your code works even as you're writing it.
The Attributes tab shows you the used attributes (including CSS) as well as the available attributes for the current tag. You can also make edits to them to get more precise. And the Tag Inspector will tell you if you're putting in invalid options.
The Behaviors tab is a very handy tab. It allows you to create and use JavaScript interactions on your Web pages. And better yet, you can download pre-built behaviors from the Macromedia developer's Web site.
The Relevant CSS tab shows more information about any CSS applied to the current item and allows you to edit it.
