Drag and Drop on QuirksMode

Peter-Paul Koch has put together yet another masterful overview, this time covering Drag and drop, something that has been on my to-do list for over a year. His script even works with just the keyboard! Not only does he offer a great Drag-and-drop script, he explains how it was written so you can better understand how Drag-and-drop works in JavaScript (and take it apart or put it together yourself).
