prev - show the previous nmh message

prev  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 circumvent this, add a profile-entry for the  link
       to your nmh profile and add the argument prev to the entry.

nmh-1.8                                            1999-04-30                                          PREV(1mh)

       If a folder is specified, it will become the current folder.   The  message  that  is  shown  (i.e.,  the
       previous message in sequence) will become the current message.

       `+folder' defaults to the current folder
       `-checkmime'
       `-header'

prev  performs a show on the previous message in the specified (or current) folder.  Like show, it passes
       any switches on to the program named by showproc or showmimeproc, which is called to  list  the  message.
       This  command  is almost exactly equivalent to “showprev”.  Consult the manual entry for show(1) for all
       the details.
