Another way to organize messages in a folder besides threading (see Threading) or using full-text indexed searches (see Searching) is by limiting the folder display to messages that are similar to the current message.
Display cheat sheet for the commands of the current prefix
in minibuffer (mh-prefix-help).
Limit to messages in the ‘tick’
sequence (mh-narrow-to-tick).
Limit to messages with the same
‘Cc:’ field
(mh-narrow-to-cc).
Limit to messages with the same
‘From:’ field
(mh-narrow-to-from).
Limit to messages with the same
‘Subject:’ field
(mh-narrow-to-subject).
Limit to messages with the same
‘To:’ field
(mh-narrow-to-to).
Remove last restriction (mh-widen).
All of the limiting commands above refine the display in some way.
The commands / c (mh-narrow-to-cc),
/ m (mh-narrow-to-from), / s
(mh-narrow-to-subject), and / t
(mh-narrow-to-to) restrict the display to messages
matching the content of the respective field in the current
message. However, you can give any of these a prefix argument to
edit the pick expression used to narrow the
view50.
You can also limit the display to messages in the
‘tick’ sequence with the command /
' (mh-narrow-to-tick). See Sequences, for information on
putting message into the ‘tick’
sequence. Use the / g
(mh-narrow-to-range) command to limit the display to
messages in a range (see Ranges).
Each limit can be undone in turn with the / w
(mh-widen) command. Give this command a prefix
argument to remove all limits.
