[Seaside] Form and checkbox?

[Carl Gundel]

Is it right that a form's values can only be captured when the form's submit 
button is clicked and that there can only be one submit button on a form?  I 
can't have a checkbox and a button both act as a submit, but have different 
callbacks, for example?

A web page can have more than one form, right?  And each can have its own 
submit button?

Sorry if these are rank beginner questions, but I am really new to web 
programming.

Thanks,
