On a web form, what should happen when the user presses the ENTER key?
<form...> tag, I have complete control over what happens with each key press. I can make it change the focus, submit the data to the server, validate the field contents, whatever. But what should it do?
Things I'm wondering: should ENTER take the user to the next field (as per TAB key)? Should pressing ENTER while focus is on the final field submit the form?
