Using the Preview Pane in Yosemite

Before Yosemite, the preview pane was only a part of the Finder's column view. But now you can use it in icon and list view as well. This makes it easy to move through a collection of photos or other documents to select the one you want. You can even watch videos or listen to audio with the preview pane. You can also look inside folders and select an item with the keyboard.
