 The URL field is actually spec'd to have embedded cancel/confirm icons in
 the right, once we have that entry control available.  That control will
 also bind the escape and enter keys to those buttons, respectively,
 solving the problem completely.

 Without that control, however, there is no way to undo changes to the URL
 at all, which means that if I accidentally type something, there's no way
 to see the correct URL again.  Fortunately, the changes don't apply when
 bookmarking or refreshing, which would make the problem much larger, but
 it does mean that you can't copy/paste the URL, or modify it
 intentionally.

 Two input events should revert any changes made to the URL field.  First,
 this should occur when the control loses focus.  Second, pressing the
 escape key should restore the current URL and select it, leaving focus
 within the entry field for further modification.

 Since it's clear from the behavior of the refresh and bookmark functions
 that this URL is in fact in memory, it shouldn't be hard to hook up these
 events.
