11.3 Message view actions ¶

As another example, suppose we would like to search for messages by the sender of the message at point:

(defun search-for-sender (msg)
  "Search for messages sent by the sender of the message at point."
  (mu4e-search
    (concat "from:"
      (mu4e-contact-email (car (mu4e-message-field msg :from))))))

;; define 'x' as the shortcut
(add-to-list 'mu4e-view-actions
  '("xsearch for sender" . search-for-sender) t)

If you wonder why we use car, remember that the From:-field is a list of (:name NAME :email EMAIL) plists; so this code gets us the e-mail address of the first in the list. From:-fields rarely have more that one address.
