Quickly preview images and other files with peep-dired

The package peep-dired lets you quickly scan through images (or any other documents) with previews in dired. In the example below, I invoke peep-dired (I bind it to P) and scan through a set of images in a dired listing. When I am finished I hit P again to quit peep-dired.

Here is my code to install and configure peep-dired with use-package

;;preview files in dired
(use-package peep-dired
  :ensure t
  :defer t ; don't access `dired-mode-map' until `peep-dired' is loaded
  :bind (:map dired-mode-map
              ("P" . peep-dired)))
