Visual Studio
Coming from the world of Vi, I prefer the incremental search over usual Ctrl + F search dialog. Didn't know it existed in VS till now. It comes out that pressing Ctrl + I in VS 2005 puts the editor in incremental search mode. To go to next match, simply press Ctrl + I again and to go to previous match, press Ctrl + I while holding down the shift key. To exit this mode, press the return key <update>you can press any key to exit this mode</update>
