Besides being a nice application launcher, LaunchBar provides Search Templates for a bunch of websites. Using these Search Templates it is possible to perform searches directly from LaunchBar without opening a web browser.

Just add the following two rules for Lexin to work.

Lexin Engelskt-Svenskt Lexikon
