I created keyword search bookmarks for all my frequently used search engines. For example, I often look up music releases on musicbrainz: http://musicbrainz.org/search?query=%s&type=release I bookmarked this URL and assigned a keyword (You can also right-click input fields and select 'Add a keyword for this search'). Now, everytime I enter "mb-r <name of the release I'm looking up>" into the url bar, it goes straight to musicbrainz and inserts my search string into the %s-placeholder.
