These "How To" documents explain in detail how to implement some of the more advanced functionality in Corvid systems. Each has a PDF document that describes specifics. Where practical, there is also a demo system you can run to see the technique in action, along with its sample code. In many cases, the sample code can even be downloaded and merged into your system to add the functionality.
