Lightroom fans love the Previous button. It does one simple thing - do-over. It basically reapplies whatever you just did to a photo, to the next photo. Camera Raw actually has a similar feature. It's not called the same thing, but it's just as useful if you quickly want to apply changes from one photo to another.
