[Ur] A few questions about form submission

[Edward Z. Yang]

1) I'd like to make a form which makes a GET request to a page
(so it takes unrestricted URL input, but the landing page is bookmarkable).
<form> appears to do POST by default and as far as I can tell
there's no way to tweak that, and obviously the AJAX ones are
not suitable.

2) When I have a ctextbox, I'd like an event to trigger when the
user presses enter.  Is there an easy way of doing that?

Cheers,
Edward
