The pretty JavaScripty stuff should just work naturally. There is a 
variable in edit_macros - 'allow_tabbing' or somesuch - that has to 
evaluate to True for the pretty stuff to work. I haven't looked in 
detail at what the conditions are on it. Look at the 'widgets' macro 
section of edit_macros.pt. Oh, and if you are overriding the 'widgets' 
macro in order to get a custom form layout, you'll lose the Javascripty 
stuff, too :( - something I wrestled with recently.
