If you're using OS X, you could call the system's quicklook. This is
what I'm using here (it works great for images or pdf files, for
instance, I'm also including the code to open the file in the external
application).
#+begin_src emacs-lisp
(defun do-ql-dwim()
(interactive)
(save-window-excursion
(let* ((proc (get-buffer-process "*Async Shell Command*")))
(if proc
(kill-process proc)
(dired-do-async-shell-command
"qlmanage -p 2>/dev/null" ""
(dired-get-marked-files))
)
(bury-buffer proc)
))
)
(defun open-in-external-app ()
"Open the current file or dired marked files in external app.
Works in Microsoft Windows, Mac OS X, Linux."
(interactive)
(let ( doIt
(myFileList
(cond
((string-equal major-mode "dired-mode") (dired-get-marked-files))
(t (list (buffer-file-name))) ) ) )
(setq doIt (if (<= (length myFileList) 5)
t
(y-or-n-p "Open more than 5 files?") ) )
(when doIt
(cond
((string-equal system-type "windows-nt")
(mapc (lambda (fPath) (w32-shell-execute "open" (replace-regexp-in-string "/" "\\" fPath t t)) ) myFileList)
)
((string-equal system-type "darwin")
(mapc (lambda (fPath) (let ((process-connection-type nil)) (start-process "" nil "open" fPath)) ) myFileList) )
((string-equal system-type "gnu/linux")
(mapc (lambda (fPath) (let ((process-connection-type nil)) (start-process "" nil "xdg-open" fPath)) ) myFileList) ) ) ) ) )
(add-hook 'dired-mode-hook (lambda ()
(define-key dired-mode-map " " 'do-ql-dwim)
(define-key dired-mode-map (kbd "C-<return>") 'open-in-external-app)
))
