13.9 Dired

It is possible to attach files to mu4e messages using dired (emacs), using the following steps (based on a post on the mu-discuss mailing list by Stephen Eglen).

(add-hook 'dired-mode-hook 'turn-on-gnus-dired-mode)

Then, mark the file(s) in dired you would like to attach and press C-c RET C-a, and you’ll be asked whether to attach them to an existing message, or create a new one.
