This section contains a few more miscellaneous commands and options.
There are times when you need to edit a message. For example, you may
need to fix a broken Content-Type header field. You can do this with
the command M (
mh-modify). It displays the raw message in
an editable buffer. When you are done editing, save and kill the
buffer as you would any other.
Commands such as
mh-pack-folder prompt to confirm whether to
process outstanding moves and deletes or not before continuing.
Turning on the option
mh-do-not-confirm-flag means that these
actions will be performed—which is usually desired but cannot be
mh-summary-height controls the number of scan lines
displayed in the MH-Folder window, including the mode line. The
default value of this option is ‘Automatic’ which means that the
MH-Folder buffer will maintain the same proportional size if the frame
is resized. If you'd prefer a fixed height, then choose the
‘Fixed Size’ option and enter the number of lines you'd like to
Normally the buffer for displaying messages is buried at the bottom at
the buffer stack. You may wish to disable this feature by turning off
mh-bury-show-buffer-flag. One advantage of not
burying the show buffer is that one can delete the show buffer more
easily in an electric buffer list because of its proximity to its
associated MH-Folder buffer. Try running M-x
electric-buffer-list to see what I mean.
Before we leave this section, I'll include a function that I use as a front end to MH-E2. It toggles between your working window configuration, which may be quite involved—windows filled with source, compilation output, man pages, and other documentation—and your MH-E window configuration. Like the rest of the customization described in this section, simply add the following code to ~/.emacs.
(defvar my-mh-screen-saved nil "Set to non-
nilwhen MH-E window configuration shown.") (defvar my-normal-screen nil "Normal window configuration.") (defvar my-mh-screen nil "MH-E window configuration.") (defun my-mh-rmail (&optional arg) "Toggle between MH-E and normal screen configurations. With non-
nilor prefix argument, inc mailbox as well when going into mail." (interactive "P") ; user callable function, P=prefix arg (setq my-mh-screen-saved ; save state (cond ;; Bring up MH-E screen if arg or normal window configuration. ;; If arg or +inbox buffer doesn't exist, run mh-rmail. ((or arg (null my-mh-screen-saved)) (setq my-normal-screen (current-window-configuration)) (if (or arg (null (get-buffer "+inbox"))) (mh-rmail) (set-window-configuration my-mh-screen)) t) ; set my-mh-screen-saved to
t;; Otherwise, save MH-E screen and restore normal screen. (t (setq my-mh-screen (current-window-configuration)) (set-window-configuration my-normal-screen) nil)))) ; set my-mh-screen-saved to nil (global-set-key "\C-x\r" 'my-mh-rmail) ; call with C-x <RET> Starting MH-E
If you type an argument (C-u) or if
nil (meaning a non-MH-E window configuration), the current
window configuration is saved, either the ‘+inbox’ buffer is
mh-rmail is run, and the MH-E window configuration
is shown. Otherwise, the MH-E window configuration is saved and the
original configuration is displayed.
 In previous versions of MH-E,
this option suppressed the confirmation in
Since this kept most users from setting this option,
mh-kill-folder was modified in version 6.0 to always ask for
confirmation subject to
 Stephen Gildea's favorite binding is (global-set-key "\C-cr" 'mh-rmail).
