Inspired by this thread I read about the Marvin app. I found out that it would be possible to define yout own online dictionary.
I bought the marvin app. and now I have a translation dictionary

I read a lot of English books, and I have really really wanted an English-Danish translation dictionary, and now I have it.

For the benefit of other Danish readers here is what I did.
1) Become a customer of
www.ordbogen.com. (I was that)
2) In Marvin set up "Other online dictionary" (see the online tutorial) and specify this command:
