WSJ + AJAX

Highlight a word and right click and it will perform a search on that word. Pretty funky. Though from a usability pov you are getting a clash of right click stuff (the default menu and WSJ's menu), and you can't move the search results window as you would a traditional window. And how would anyone know the function is there. Still, a sign of things to come.
