If the message under the cursor is already displayed, this command
|
||
scrolls to the beginning of the message. MH-E normally hides a lot of
|
||
the superfluous header fields that mailers add to a message, but if
|
||
you wish to see all of them, use the command \\[mh-header-display].
|
||
|
||
Two hooks can be used to control how messages are displayed. The
|
||
first hook, `mh-show-mode-hook', is called early on in the
|
||
process of the message display. It is usually used to perform
|
||
some action on the message's content. The second hook,
|
||
`mh-show-hook', is the last thing called after messages are
|
||
displayed. It's used to affect the behavior of MH-E in general or
|
||
when `mh-show-mode-hook' is too early.
|
||
|
||
From a program, optional argument MESSAGE can be used to display an
|
||
alternative message. The optional argument REDISPLAY-FLAG forces the
|
||
redisplay of the message even if the show buffer was already
|
||
displaying the correct message.
|
||
|
||
See the \"mh-show\" customization group for a litany of options that
|

control what displayed messages look like."
