Here's another one for Google lovers just like me, because definitely there are times when I have to launch a new browser window just for making a google search, this should work quite nice... I haven't installed it yet but should give it a try in the next few minutes, sounds pretty handy to me:

[COLOR=royalblue]Google Deskbar enables you to search with Google from any application without lifting your fingers from the keyboard.
* Search using Google, even when your browser isn't running
* Preview search results in a small inset window that closes automatically
* Access Google from any application by typing Ctrl+Alt+G
* Use keyboard shortcuts for multiple Google searches, i.e., Google News (Ctrl+N),Google Images (Ctrl+I), or Froogle (Ctrl+F)[/COLOR]
