Reading Digests
...............

   A digest is a message that contains other messages.  Special mh-e
commands let you read digests conveniently.  You can use <SPC> and
<DEL> to page through the digest as if it were a normal message, but if
you wish to skip to the next message in the digest, use `M-SPC'
(`mh-page-digest').  To return to a previous message, use `M-DEL'
(`mh-page-digest-backwards').

   Another handy command is `M-b' (`mh-burst-digest').  This command
uses the MH command `burst' to break out each message in the digest
into its own message.  Using this command, you can quickly delete
unwanted messages, like this: Once the digest is split up, toggle out
of MH-Folder Show mode with `t' (see Moving Around.) so that the
scan lines fill the screen and messages aren't displayed.  Then use `d'
(see Deleting.) to quickly delete messages that you don't want to
read (based on the `Subject:' header field).  You can also burst the
digest to reply directly to the people who posted the messages in the
digest.  One problem you may encounter is that the `From:' header
fields are preceded with a `>' so that your reply can't create the
`To:' field correctly.  In this case, you must correct the `To:' field
yourself.  This is described later in See Editing Textual.
