Many string or integer options are easy to modify using M-x
customize-option. For example, to modify the option that controls
printing, you would run M-x customize-option <RET>
mh-lpr-command-format <RET>. In the buffer that appears, modify
the string to the right of the variable. For example, you may change
the lpr command with `nenscript -G -r -2 -i'%s''. Then
use the `State' combo box and select `Save for Future
Sessions'. To read more about mh-lpr-command-format
, see
Printing.
Options can also hold boolean values. In Emacs Lisp, the boolean
values are nil
, which means false, and t
, which means
true. The customize-option
function makes it easy to change
boolean values; simply click on the toggle button in the customize
buffer to switch between `on' (t
) and `off'
(nil
). For example, try setting mh-bury-show-buffer-flag
to `off' to keep the MH-Show buffer at the top of the buffer
stack. Use the `State' combo box and choose `Set for Current
Session' to see how the option affects the show buffer. Then choose
the `Erase Customization' menu item to reset the option to the
default, which places the MH-Show buffer at the bottom of the buffer
stack.
The text usually says to turn on an option by setting it to a
non-nil
value, because sometimes values other than
`on' are meaningful. An example of this is the variable
mh-mhl-format-file
(see Viewing). Other options, such as
hooks, involve a little more Emacs Lisp programming expertise.
You can browse all of the MH-E options with the customize-group
function. Try entering M-x customize-group <RET> mh
<RET> 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 M-x mh-customize <RET>.
