Once a message has been selected, VM will show it to you. By default, presentation is done in two stages: previewing and paging.
| 3.1 Previewing | Customizing message previews. | |
| 3.2 Paging | Scrolling through the current message. | |
| 4. Reading MIME Messages | Using VM's MIME display features. |

Previewing means showing you a small portion of a message and allowing you to decide whether you want to read it. Typing <SPC> exposes the body of the message, and from there you can repeatedly type <SPC> to page through the message.
By default, the sender, recipient, subject and date headers are shown
when previewing; the rest of the message is hidden. This behavior may
be altered by changing the settings of three variables:
vm-visible-headers, vm-invisible-header-regexp and
vm-preview-lines.
If the value of vm-preview-lines is a number, it tells VM how
many lines of the text of the message should be visible. The default
value of this variable is 0. If vm-preview-lines is nil,
then previewing is not done at all; when a message is first presented it
is immediately exposed in its entirety and is flagged as read. If
vm-preview-lines is t, the message body is displayed fully
but the message is not flagged as read until you type <SPC>.
The value of vm-visible-headers should be a list of regular
expressions matching the beginnings of headers that should be made
visible when a message is presented. The regexps should be listed in
the preferred presentation order of the headers they match.
If non-nil, the variable vm-invisible-header-regexp
specifies what headers should not be displayed. Its value should
be a string containing a regular expression that matches all headers you
do not want to see. Setting this variable non-nil implies that
you want to see all headers not matched by it; therefore the value of
vm-visible-headers is only used to determine the order of the
visible headers in this case. Headers not matched by
vm-invisible-header-regexp or vm-visible-headers are
displayed last.
If you change the value of either vm-visible-headers or
vm-invisible-header-regexp in the middle of a VM session the
effects will not be immediate. You will need to use the command
vm-discard-cached-data on each message (bound to j by
default) to force VM to rearrange the message headers. A good way to do
this is to mark all the messages in the folder and apply
vm-discard-cached-data to the marked messages. See section Message Marks.
Another variable of interest is vm-highlighted-header-regexp.
The value of this variable should be a single regular expression that
matches the beginnings of any header that should be presented in inverse
video when previewing. For example, a value of
‘"^From\\|^Subject"’ causes the From and Subject headers to be
highlighted. Highlighted headers will be displayed using the face
specified by vm-highlighted-header-face, which defaults to
'bold.
By default, VM will not preview messages that are flagged as read. To
have VM preview all messages, set the value of
vm-preview-read-messages to t.
Typing t (vm-expose-hidden-headers) makes VM toggle
between exposing and hiding headers that would ordinarily be hidden.

Typing <SPC> during a message preview exposes the body of the
message. If the message was new or previously unread, it will be
flagged “read”. At this point you can use <SPC> to scroll
forward, and b or <DEL> to scroll backward a windowful of
text at a time. A prefix argument n applied to these commands
causes VM to scroll forward or backward n lines. Typing space
at the end of a message moves you to the next message. If the value
of vm-auto-next-message is nil, <SPC> will not
move to the next message; you must type n explicitly.
If the value of vm-honor-page-delimiters is non-nil, VM
will recognize and honor page delimiters. This means that when you
scroll through a document, VM will display text only up to the next page
delimiter. Text after the delimiter will be hidden until you type
another <SPC>, at which point the text preceding the delimiter will
become hidden. The Emacs variable page-delimiter determines what
VM will consider to be a page delimiter.
You can “unread” a message (so to speak) by typing U
(vm-unread-message). The current message will be flagged
unread.
Sometimes you will receive messages that contain lines that are
too long to fit on your screen without wrapping. If you set
vm-fill-paragraphs-containing-long-lines to a positive
numeric value N, VM will call fill-paragraph on all
paragraphs that contain lines spanning N columns or more.
As with other things VM does that modifies the way the
message looks on the screen, this does not change message
contents. VM copies the message contents to a “presentation”
buffer before altering them. The fill column that VM uses is
controlled by vm-paragraph-fill-column. Unlike the Emacs
variable fill-column, this variable is not buffer-local
by default.
