This question already has an answer here:
Does anyone know how to turn off the auto search in nautilus 3.8. In previous versions when I pressed a key it would select the first item that started with that letter/key in directory I was in. Now if I do this is automatically preforms a search as filters all items which is really annoying (and slow). Does anyone know how to turn this off and revert to the old behavior. I checked preferences but there's nothing there.
