Dilo looks up words at http://dict.leo.org and shows the english or german translation of that word. It is kind of comparable to "Babylon"� for Windows�, but uses a public web-dictionary instead of having a local one. if you want to see how LEO works, please go to http://dict.leo.org and try it out yourself.
You can start up Dilo directly and enter something into the search field to search for or you can call it through the services menu Define in Dilo.
It doesn't matter whether you are searching for an english description of a german word or vice versa (and french/german respectively). Just select the word in the editor you are using, choose "Services->Define in Dilo" (or "Services->Define French in Dolo") and that's it.
