If you have never seen CodeRush in action you should check out the video in Jackie Goldstein’s blog post. This was created when he asked Kim Major to do a presentation.
The effect is pretty cool. Now I use Refactor and CodeRush but I am nowhere as fast as this, even with practice 
Guess I should study up on all the hotkeys as I saw quite a few I don’t know about.
BTW CodeRush and Refactor are created by Mark Miller, an amazing guy in more than one way 
Enjoy!
