Here’s a feature introduced in Coda 1.5 that might be new to you (after all the big focus of that release was SVN integration and global find/replace). The new books feature allows you to add new online reference and even reset the defaults if you wish.
Let’s take Sitepoint’s excellent CSS reference as the example:

- First, Command-6 to go to the books view, and click the add icon bottom left. In the sheet that appears, enter the title and URL (e.g http://reference.sitepoint.com/css). You can also drag in an image to represent it (which looks rather sexy).
- Next, in the ‘use for mode’, select the language it references if it’s available. In this example, ‘CSS’, which will override the default choice.
- Finally, add the search URL. You can easily discover this by searching for * on the site in question and copying the resulting URL.
Now if there is a CSS property I want more information on, I can either search within the books view in Coda, or select the property in code view and choose ‘Look up in Reference Books’ from the context menu. This is something I do a lot, mainly to check the support for the property in other browsers.
