What is it? Where is it documented? How do I register a handler for an application-specific high-level event and how do I send that event to fire the handler? Can I add other details to the event itself or do I need a separate queue for additional information?

See Re^5: Tk programmatically monitor change in Listbox for hints, but i wouldnt say it was documented as you might like it, but the basis for those tests is found in the TCL pod.
