The default binding for view-attachments is `v', which displays the
attachment menu for a message. The attachment menu displays a list of
the attachments in a message. From the attachment menu, you can save,
print, pipe, delete, and view attachments. You can apply these
operations to a group of attachments at once, by tagging the attachments
and by using the ``tag-prefix'' operator. You can also reply to the
current message from this menu, and only the current attachment (or the
attachments tagged) will be quoted in your reply. You can view
attachments as text, or view them using the mailcap viewer definition.
Finally, you can apply the usual message-related functions (like
resend-message, and the reply
and forward functions) to attachments of type message/rfc822.
See the help on the attachment menu for more information.
