Automatic Lookup From Emacs

Xah Lee has released an interesting package called lookup-word-on-internet.el, which he describes on his Web site here. It will take the word at point or a phrase in an active region and look it up in Google, Wikipedia, Dict.org, Answers.com, Wiktionary, or PHP.net.

Basically, there is a little service-specific routine you can call for each service and they¹, in turn, call a worker function to do the real work. The service-specific routines are

Of course, for these to be useful, you should bind them to convenient key sequences.

I have a couple of functions like these in my init.el file but this package gives you a fairly comprehensive set in one convenient package and also provides a framework that makes it easy to add your own service-specific functions for sites not in the list.
