Firefox 3.0 Extension WikiLook Makes You Smart On The Fly

Sick of typing "def: wicked awesome" into Google? Really want the definition of "crunk" right away? Wait no longer: the new Firefox 3.0 extension WikiLook grants you access to Wikipedia instantly.
The process is simple. Download WikiLook from the Firefox Extensions page. Locate the word you need defined. Hold down the Shift key and lightly graze the word with your mouse pointer—think of it as petting the word lovingly, like a soft purring kitten. Wait half a second and a green window should pop up, handing over your definition.
The process takes a little getting used to and may be unnecessary for wicked awesome people who know everything already.

I think an even better add-on is the Hyperwords add-on for Firefox. With that one you can double click a word or highlight a phrase and it gives you a lot more reference options.
It will give you the option to search Google and Wikipedia. It also gives you a pop-up dialog box somewhat similar to this one so you can check it out before deciding if you want to go to either of those sites. Also if you see a product listed on a page, it provides an option to go to Amazon to check it out further.
