[Zope] "magic buttons" in forms

Two questions about "magic" behavior of form submit buttons: 1)The "cancel" button system, can it be made to work with a button with another value apart from "cancel"? (such as "back" or "home") 2)The <imput type=submit name="foo:method"> system, please can someone explain this, as it is the only way I have yet figured out to do a single form with many destination pages. Also, does this behave differently in DTML methods and DTML documents? --- Julian Morrison Programmer (Zereau Ltd)
