In this mode, basically, the message is composed in the tagged MIME
format. The message tag looks like:
- `--[[text/plain; charset=ISO-2022-JP][7bit]]'.
+ --[[text/plain; charset=ISO-2022-JP][7bit]]
The tag specifies the MIME content type, subtype, optional parameters
and transfer encoding of the message following the tag. Messages
which key is MIME charset and value is coding-system.
Following commands are available in addition to major mode commands:
+
+\[make single part\]
\\[mime-editor/insert-text] insert a text message.
\\[mime-editor/insert-file] insert a (binary) file.
\\[mime-editor/insert-external] insert a reference to external body.
\\[mime-editor/insert-message] insert a mail or news message.
\\[mime-editor/insert-mail] insert a mail message.
\\[mime-editor/insert-signature] insert a signature file at end.
