<p><a name="index-Emacs_002c-customizing-217"></a><a name="index-Emacs_002c-setting-options-218"></a><a name="index-customizing-MH_002dE-219"></a><a name="index-setting-options-220"></a><a name="index-customize_002doption-221"></a><a name="index-mh_002dlpr_002dcommand_002dformat_002c-example-222"></a>
Many string or integer options are easy to modify using <kbd>M-x
customize-option</kbd>. For example, to modify the option that controls
printing, you would run <kbd>M-x customize-option <RET>
mh-lpr-command-format <RET></kbd>. In the buffer that appears, modify
the string to the right of the variable. For example, you may change
the <samp><span class="command">lpr</span></samp> command with `<samp><span class="samp">nenscript -G -r -2 -i'%s'</span></samp>'. Then
use the `<samp><span class="samp">State</span></samp>' combo box and select `<samp><span class="samp">Save for Future
Sessions</span></samp>'. To read more about <code>mh-lpr-command-format</code>, see
<a href="Printing.html#Printing">Printing</a>.
<p><a name="index-nil-223"></a><a name="index-off_002c-option-224"></a><a name="index-on_002c-option-225"></a><a name="index-option_002c-turning-on-and-off-226"></a><a name="index-t-227"></a><a name="index-customize_002doption-228"></a><a name="index-mh_002dbury_002dshow_002dbuffer_002dflag_002c-example-229"></a>
Options can also hold boolean values. In Emacs Lisp, the boolean
values are <code>nil</code>, which means false, and <code>t</code>, which means
true. The <code>customize-option</code> function makes it easy to change
boolean values; simply click on the toggle button in the customize
buffer to switch between `<samp><span class="samp">on</span></samp>' (<code>t</code>) and `<samp><span class="samp">off</span></samp>'
(<code>nil</code>). For example, try setting <code>mh-bury-show-buffer-flag</code>
to `<samp><span class="samp">off</span></samp>' to keep the MH-Show buffer at the top of the buffer
stack. Use the `<samp><span class="samp">State</span></samp>' combo box and choose `<samp><span class="samp">Set for Current
Session</span></samp>' to see how the option affects the show buffer. Then choose
the `<samp><span class="samp">Erase Customization</span></samp>' menu item to reset the option to the
default, which places the MH-Show buffer at the bottom of the buffer
stack.
<p><a name="index-mh_002dmhl_002dformat_002dfile_002c-example-230"></a>
The text usually says to turn on an option by setting it to a
<em>non-</em><code>nil</code> value, because sometimes values other than
`<samp><span class="samp">on</span></samp>' are meaningful. An example of this is the variable
<code>mh-mhl-format-file</code> (see <a href="Viewing.html#Viewing">Viewing</a>). Other options, such as
hooks, involve a little more Emacs Lisp programming expertise.
<p><a name="index-customization-group_002c-_0040samp_007bmh_007d-231"></a><a name="index-g_t_0040samp_007bmh_007d-customization-group-232"></a><a name="index-customize_002dgroup-233"></a><a name="index-mh_002dcustomize-234"></a>
You can browse all of the MH-E options with the <code>customize-group</code>
function. Try entering <kbd>M-x customize-group <RET> mh
<RET></kbd> to view the top-level options as well as buttons for all of
the MH-E customization groups. Another way to view the MH-E
customization group is to use <kbd>M-x mh-customize <RET></kbd>.
