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.
