KallOut, which exhibited in the TechCrunch50 demo pit last week, has developed a way to make search even faster: users can double click on a word or phrase within any web page or e-mail to look it up.A drop down menu appears next to the selection with results from the top search engines, and users can select which one they would like to use, CEO Lee Lorenzen says. TechCrunch reporter Don Reisinger wrote that KallOut was just as noteworthy as some of the presenters on-stage, and Rafe Needleman at CNET recommends it for looking up references while writing. --Kelsey Blodget Less
