I haven’t used yahoo search too much in quite a while, but there is an interesting post in their search blog about Yahoo Shortcuts. An example is typing in !ebay lamps takes you to ebay.com and searches for lamps. (Part of me is asking, why not just go to ebay and search for lamps??? – but there are some interesting uses for this within a toolbar – I can imagine it would get you there a step or two more quickly.)
