From the developer:
This is a simple extension for Safari 5.1 and above to enable keyword search from the address bar.
To edit or delete these, or add your own, right-click any web page and select "Keyword Search Settings". Here you can add keywords and search URLs, and delete or modify the existing ones. Put @@@ in the search URL to insert the search string, or use %%% if you want spaces to be encoded as %20 instead of +.
