<h3 class="section">6.9 Miscellaneous Commands and Options</h3>
<p>This section contains a few more miscellaneous commands and options.
<p><a name="index-editing-message-747"></a><a name="index-mh_002dmodify-748"></a><a name="index-M-749"></a>
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 <kbd>M</kbd> (<code>mh-modify</code>). It displays the raw message in
an editable buffer. When you are done editing, save and kill the
buffer as you would any other.
<p><a name="index-mh_002dkill_002dfolder-750"></a><a name="index-mh_002dpack_002dfolder-751"></a><a name="index-mh_002ddo_002dnot_002dconfirm_002dflag-752"></a>
Commands such as <code>mh-pack-folder</code> prompt to confirm whether to
process outstanding moves and deletes or not before continuing.
Turning on the option <code>mh-do-not-confirm-flag</code> means that these
actions will be performed—which is usually desired but cannot be
retracted—without question<a rel="footnote" href="#fn-1" name="fnd-1"><sup>1</sup></a>.
<p><a name="index-MH_002dFolder-mode-753"></a><a name="index-modes_002c-MH_002dFolder-754"></a><a name="index-mh_002dsummary_002dheight-755"></a>
The option <code>mh-summary-height</code> controls the number of scan lines
displayed in the MH-Folder window, including the mode line. The
default value of this option is `<samp><span class="samp">Automatic</span></samp>' 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
`<samp><span class="samp">Fixed Size</span></samp>' option and enter the number of lines you'd like to
see.
<p><a name="index-mh_002dbury_002dshow_002dbuffer_002dflag-756"></a>
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
the option <code>mh-bury-show-buffer-flag</code>. 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 <kbd>M-x
electric-buffer-list</kbd> to see what I mean.
<p><a name="index-g_t_0040file_007b_002eemacs_007d-757"></a><a name="index-files_002c-_0040file_007b_002eemacs_007d-758"></a><a name="index-reading-mail-759"></a>
Before we leave this section, I'll include a function that I use as a
front end to MH-E<a rel="footnote" href="#fn-2" name="fnd-2"><sup>2</sup></a>. 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 <samp><span class="file">~/.emacs</span></samp>.
<p><a name="index-mh_002drmail_002c-example-760"></a>
<pre class="smalllisp"> (defvar my-mh-screen-saved nil
"Set to non-<code>nil</code> when 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-<code>nil</code> or prefix argument, <i>inc</i> mailbox as well
when going into mail."
(interactive "P") ; <span class="roman">user callable function, P=prefix arg</span>
(setq my-mh-screen-saved ; <span class="roman">save state</span>
(cond
;; <span class="roman">Bring up MH-E screen if arg or normal window configuration.</span>
;; <span class="roman">If arg or +inbox buffer doesn't exist, run mh-rmail.</span>
((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) ; <span class="roman">set my-mh-screen-saved to </span><code>t</code>
;; <span class="roman">Otherwise, save MH-E screen and restore normal screen.</span>
(t
(setq my-mh-screen (current-window-configuration))
(set-window-configuration my-normal-screen)
nil)))) ; <span class="roman">set my-mh-screen-saved to nil</span>
(global-set-key "\C-x\r" 'my-mh-rmail) ;<span class="roman"> call with C-x <RET></span>
<i>Starting MH-E</i>
</pre>
<p>If you type an argument (<kbd>C-u</kbd>) or if <code>my-mh-screen-saved</code> is
<code>nil</code> (meaning a non-MH-E window configuration), the current
window configuration is saved, either the `<samp><span class="samp">+inbox</span></samp>' buffer is
displayed or <code>mh-rmail</code> is run, and the MH-E window configuration
is shown. Otherwise, the MH-E window configuration is saved and the
original configuration is displayed.

<h4>Footnotes</h4><p class="footnote"><small>[<a name="fn-1" href="#fnd-1">1</a>]</small> In previous versions of MH-E,
this option suppressed the confirmation in <code>mh-kill-folder</code>.
Since this kept most users from setting this option,
<code>mh-kill-folder</code> was modified in version 6.0 to always ask for
confirmation subject to <code>mh-kill-folder-suppress-prompt-hook</code>.
See <a href="Folders.html#Folders">Folders</a>.</p>
<p class="footnote"><small>[<a name="fn-2" href="#fnd-2">2</a>]</small> Stephen Gildea's favorite binding is
<kbd>(global-set-key "\C-cr" 'mh-rmail)</kbd>.</p>
