Another example of using the wacsui module can be found in the newsets.php application in the samples directory. This is a more "real world" worked example showing a new releases index page; it makes use of both the iconlink and addkeyicons functions.
Detailed documentation on each call available and how it works can be found in the API reference section Chapter 9, WACS API: User Interface Module. Another good source of examples of how to utilise these functions is to be found in the the section called “Wacs-PHP: The Simple Skin” provided as part of the Wacs-PHP API library. And of course don't forget that you can always look at how the main WACS user environment applications themselves make use of these functions.
