Thanks to all for these great tips! If anyone has found similar plug-ins or add-ons for Google Chrome, please post them. I would really like something to translate just a single word with a click. I think this would be a good compromise to help with learning instead of just pasting into Google translate and getting something ok, but not quite perfect. The company I work for uses Google for our email and having the ability to translate built in is helpful but on the other hand it takes away some of the "forced learning".

These translation tools are getting better all the time however, the prepositions (of, from, about, etc) are always a problem since every culture/language is different, and one of those things "you just have to memorize" when learning a language.
