Calling all Javascript Masters

In a normal form, there is a submit button that delivers all of the
values of the form objects to the called method. Same is true for an
ajax form. Quite often with ajax though, you want to have other
buttons or links on the page that change the form in some way, often
dependent on the value of one or more form elements. Unfortunately, a
regular "LinkToRemote" does not provide any useful form related params
to the called method.
