18 Using Sequences
******************
For the whole scoop on MH sequences, refer to ‘mh-sequence’(5)(1). As
you’ve read, several of the MH-E commands can operate on a sequence,
which is a shorthand for a range or group of messages. For example, you
might want to forward several messages to a friend or colleague. Here’s
how to manipulate sequences. These commands are also available in the
‘Sequence’ menu.
‘'’
Toggle tick mark of range (‘mh-toggle-tick’).
‘S ?’
Display cheat sheet for the commands of the current prefix in
minibuffer (‘mh-prefix-help’).
‘S '’
Limit to ticked messages (‘mh-narrow-to-tick’).
‘S d’
Delete range from sequence (‘mh-delete-msg-from-seq’).
‘S k’
Delete sequence (‘mh-delete-seq’).
‘S l’
List all sequences in folder (‘mh-list-sequences’).
‘S n’
Restrict display to messages in sequence (‘mh-narrow-to-seq’).
‘S p’
Add range to sequence (‘mh-put-msg-in-seq’).
‘S s’
Display the sequences in which the current message appears
(‘mh-msg-is-in-seq’).
‘S w’
Remove last restriction (‘mh-widen’).
‘M-x mh-update-sequences’
Flush MH-E’s state out to MH.
The ‘mh-sequences’ customization group contains the options
associated with sequences.
‘mh-refile-preserves-sequences-flag’
On means that sequences are preserved when messages are refiled
(default: ‘on’).
‘mh-tick-seq’
The name of the MH sequence for ticked messages (default: ‘'tick’).
‘mh-update-sequences-after-mh-show-flag’
On means flush MH sequences to disk after message is shown
(default: ‘on’).
‘mh-whitelist-preserves-sequences-flag’
On means that sequences are preserved when messages are whitelisted
(default: ‘on’).
The following hook is available.
‘mh-unseen-updated-hook’
Hook run after the unseen sequence has been updated (default:
‘nil’).
To place a message in a sequence, use ‘S p’ (‘mh-put-msg-in-seq’).
Give ‘S p’ a range and you can add all the messages in a sequence to
another sequence (for example, ‘C-u S p SourceSequence <RET>
DestSequence <RET>’, 
Ranges).
One specific use of the ‘S p’ command is ‘'’ (‘mh-toggle-tick’) which
adds messages to the ‘tick’ sequence. This sequence can be viewed later
with the ‘F '’ (‘mh-index-ticked-messages’) command (Folders).
You can customize the option ‘mh-tick-seq’ if you already use the
‘tick’ sequence for your own use. You can also disable all of the
ticking functions by choosing the ‘Disable Ticking’ item but there isn’t
much advantage to that.
Once you’ve placed some messages in a sequence, you may wish to
narrow the field of view to just those messages in the sequence you’ve
created. To do this, use ‘S n’ (‘mh-narrow-to-seq’). You are prompted
for the name of the sequence. What this 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. To
narrow the view to the messages in the ‘tick’ sequence, use ‘S '’
(‘mh-narrow-to-tick’). When you want to widen the view to all your
messages again, use ‘S w’ (‘mh-widen’).
You can see which sequences in which a message appears with the
command ‘S s’ (‘mh-msg-is-in-seq’). Use a prefix argument to display
the sequences in which another message appears (as in ‘C-u 42 S s
<RET>’). Or, you can list all sequences in a selected folder (default
is current folder) with ‘S l’ (‘mh-list-sequences’). The list appears
in a buffer named ‘*MH-E Sequences*’ (Miscellaneous).
If a message is in any sequence (except ‘Previous-Sequence:’(2) and
‘cur’) when it is refiled, then it will still be in those sequences in
the destination folder. If this behavior is not desired, then turn off
the option ‘mh-refile-preserves-sequences-flag’.
If you want to remove a message (or range, Ranges) from a
sequence, use ‘S d’ (‘mh-delete-msg-from-seq’). If you want to delete
an entire sequence, use ‘S k’ (‘mh-delete-seq’). In the latter case you
are prompted for the sequence to delete. Note that this deletes only
the sequence, not the messages in the sequence. If you want to delete
the messages, use ‘C-u d’ (Reading Mail).
Three sequences are maintained internally by MH-E and pushed out to
MH when a message is shown. They include the sequence specified by your
‘Unseen-Sequence:’ profile component, ‘cur’, and the sequence listed by
the option ‘mh-tick-seq’ which is ‘tick’ by default. If you do not like
this behavior, turn off the option
‘mh-update-sequences-after-mh-show-flag’. You can then update the state
manually with the ‘x’, ‘q’, or ‘M-x mh-update-sequences’ commands.
The hook ‘mh-unseen-updated-hook’ is run after the unseen sequence
has been updated. The variable ‘mh-seen-list’ can be used by this hook
to obtain the list of messages which were removed from the unseen
sequence.
With the exceptions of ‘S n’ and ‘S w’, the underlying MH command
dealing with sequences is ‘mark’(3).
