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.
+\\[mime-editor/insert-key] insert PGP public key.
\\[mime-editor/insert-tag] insert a new MIME tag.
+
+\[make enclosure (maybe multipart)\]
\\[mime-editor/enclose-alternative-region] enclose as multipart/alternative.
\\[mime-editor/enclose-parallel-region] enclose as multipart/parallel.
\\[mime-editor/enclose-mixed-region] enclose as multipart/mixed.
\\[mime-editor/enclose-digest-region] enclose as multipart/digest.
\\[mime-editor/enclose-signed-region] enclose as PGP signed.
\\[mime-editor/enclose-encrypted-region] enclose as PGP encrypted.
-\\[mime-editor/insert-key] insert PGP public key.
+\\[mime-editor/enclose-quote-region] enclose as verbose mode (to avoid to expand tags)
+
+\[other commands\]
+\\[mime-editor/set-transfer-level-7bit] set transfer-level as 7.
+\\[mime-editor/set-transfer-level-8bit] set transfer-level as 8.
+\\[mime-editor/set-split] set message splitting mode.
+\\[mime-editor/set-sign] set PGP-sign mode.
+\\[mime-editor/set-encrypt] set PGP-encryption mode.
\\[mime-editor/preview-message] preview editing MIME message.
\\[mime-editor/exit] exit and translate into a MIME compliant message.
-\\[mime-editor/maybe-translate] exit and translate if in MIME mode, then split.
