Hi,
Attached are two patches that make shift+tab cycle backwards through
completion-enabled awful prompt widgets. The first enables shift+tab to
be caught by the keygrabber (it actually sends ISO_Left_Tab, so I have a
special case that transforms that to a plain old tab), and the second
uses this to add the cycling behavior to the prompt.
