mh-display-with-external-viewer
mh-display-with-external-viewer is an interactive autoloaded compiled Lisp function in `mh-mime.el
'.
(mh-display-with-external-viewer PART-INDEX)
View attachment externally.
If Emacs does not know how to view an attachment, you could save
it into a file and then run some program to open it. It is
easier, however, to launch the program directly from MH-E with
this command. While you'll most likely use this to view
spreadsheets and documents, it is also useful to use your browser
to view HTML attachments with higher fidelity than what Emacs can
provide.
This command displays the attachment associated with the button
under the cursor. If the cursor is not located over a button,
then the cursor first moves to the next button, wrapping to the
beginning of the message if necessary. You can provide a numeric
prefix argument PART-INDEX to view the attachment labeled with
that number.
This command tries to provide a reasonable default for the viewer
by calling the Emacs function `mailcap-mime-info'. This function
usually reads the file "/etc/mailcap".
