Today I just see that Google is doing keyboard shortcut feature for their search result page. Although now it's in google lab and just a experimental feature but I think it will be out of the lab soon. It's a good news for keyboard-centric user like me. :D So my
GoogleSurfKey script will be outdated soon.
You can try this new Google's experimental feature out at the
Google Experimental page. Now it can use only in main english google.
