Quickly Switch Between HTML and Plain Text in mu4e 

Last updated on December 29, 2024

Mu4e defaults loading messages in HTML with shr. While this works well most of the time, sometimes a plain text version is more readable. Therefore, it is desirable to create a key binding to switch between these two versions.

I have the following in my Emacs configuration:

;; Quickly switching between plain text and HTML mime type.
(keymap-set mu4e-view-mode-map (kbd "K")
            (lambda ()
              (interactive)
              (gnus-article-jump-to-part 1)
              (gnus-article-press-button)
              (gnus-article-press-button)))

This binds key Shift+K to switch between plain text and HTML versions of a message, if the message has both versions available.
