Add Keyword Search to Safari with Keywurl

Mac OS X only: Freeware Safari plug-in Keywurl brings the time-saving convenience of keyword searches to Safari, allowing users to type something like imdb Semi-Pro into the address bar to search IMDB rather than first going to the home page. Granted, this functionality comes built in to Firefox, and with a few tweaks to Firefox you can really supercharge your address bar with keyword bookmarks and searches, but for anyone who sticks with Safari for its raw speed and Mac-ness, Keywurl is a must-have. Keywurl is freeware, Mac OS X only.
