Google has an experimental search page
where you can test drive new search result layouts. My favorite is the
Keyboard Shortcuts option. This lets you navigate and view search results
using only the keyboard - no mouse required! It's a huge benefit for
Quicksilver fans.
Now that Yahoo! is my default search engine, I desperately didn't want to give
up the keyboard shortcuts feature. Thanks to jQuery and
Greasemonkey I don't have to.
Make sure you're using Firefox and have the Greasemonkey plugin loaded. Then,
click here to install.
I've chosen the same shortcut keys as Google. J and K move you up and
down through the search results. Press return to view the selected link.
You can even browse through multiple pages when you hit the end of the
results. Pressing / will jump you to the search box if you'd like to run a
new search. Hit escape to move back to the results.
You can view the source on Google Code.
