;;; Commentary:
|
|
|
|
;; Putting these functions in a separate file lets MH-E start up faster,
|
|
;; since less Lisp code needs to be loaded all at once.
|
|
|
|
;; Please add the functions in alphabetical order. If only one or two
|
|
;; small support routines are needed, place them with the function;
|
|
;; otherwise, create a separate section for them.

"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."
