mh-narrow-to-seq is an interactive autoloaded compiled Lisp function in `mh-seq.el
'.
(mh-narrow-to-seq SEQUENCE)
Restrict display to messages in SEQUENCE.
You are prompted for the name of the sequence. What this command
does is show only those messages that are in the selected
sequence in the MH-Folder buffer. In addition, it limits further
MH-E searches to just those messages.
When you want to widen the view to all your messages again, use
M-x mh-widen.
