- "Burst apart the current message, which should be a digest.
-The message is replaced by its table of contents and the messages from the
-digest are inserted into the folder after that message."
+ "Break up digest into separate messages\\<mh-folder-mode-map>.
+
+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
+\\[mh-toggle-showing] so that the scan lines fill the screen and
+messages aren't displayed. Then use \\[mh-delete-msg] 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."
