prev - show the previous message (only available within the message han-
dling system, mh)
prev [+folder] [-[no]header] [-help] [-showproc program] [-noshowproc]
[options to showproc]
Displays a one-line header before the message. The header consists of
the name of the folder and the message number. This is the default
behavior. It can be suppressed with the -noheader option.
Prints a list of the valid options to this command.
-showproc program [ options ]
Specifies an alternative program to list messages. The default is to
use the program defined by the showproc: entry in the .mh_profile file.
As with show, you can give options to the showproc program at the com-
mand line. These are passed directly to showproc by prev.
The defaults for this command are:
+folder defaults to the current folder
The prev command displays the previous message in the current folder. The
previous message is the one before the current message in the folder. The
message that is shown becomes the current message.
You can specify a folder other than the current folder by using the +folder
argument. If you specify a folder, that becomes the current folder.
The prev command is really a link to the show program. As a result, if you
make a link to prev and that link is not called prev, your link will act
like show instead. To avoid this, add a profile-entry for the link to your
MH profile and add the argument prev to the entry.
