In some cases I prefer to edit files using Markdown rather than Org Mode. Marked App works great for previewing Markdown and quickly sharing or saving in various formats.
The Marked Bonus Pack contains a bit of Lisp for sending my current Emacs buffer to Marked for preview…
(defun markdown-preview-file () "use Marked 2 to preview the current file" (interactive) (shell-command (format "open -a 'Marked 2.app' %s" (shell-quote-argument (buffer-file-name)))) ) (global-set-key "\C-cm" 'markdown-preview-file)
Now I just hit “C-c m” and the current buffer is instantly previewed in Marked App. Nice.
