Ask yourself "Do
I feel lucky?". Well, do ya, punk?
If so, you should immediately install one of these: IFL syntax pseudo-protocol for Windows (download) or for links.
Oh, you want to know what it does first? Ok. It enables your computer to understand some special keyword-based URLs (URIs?) like these, by effectively passing the keywords to google and hitting "I'm feeling lucky":
Mentioning fish.cx might help if they haven't come across it before.
And in the spirit of credit where it's due, Mark Longair did the Windows implementation and Chris Lightfoot did the patch for links. I just came up with the idea.
Google themselves are using ifl-style links on their pages. Their "PigeonRank technology" page (ifl:pigeonrank) contains this text:
"PigeonRank's success relies primarily on the superior trainability of the domestic pigeon (Columba livia) and its unique capacity to recognize objects regardless of spatial orientation."
The "spatial orientation" link goes to http://www.google.com/search?hl=en&q=pigeons+mental+rotations, which is the list of google's results for the search "pigeons mental rotations". Clearly what they needed was an "ifl:pigeons+mental+rotations" link.
You should bear in mind when using these that you should try to provide enough keywords that it will remain valid for a suitably long time. While something like ifl:dubya+sucks is likely to remain valid in general, it doesn't narrow it down well to a particular page. This can be tricky, which is why I think google should store good search terms with the first page it returns and display them next to links. I've suggested it to them twice, but they ignored me :-/ So I encourage anyone reading this to lobby on my behalf: email@example.com.
