elm, or by
selecting it from the menu. The program will read in your incoming mailbox
(/usr/spool/mail/yourname, or whatever you set in the variable
$MAIL), and display the subjects of the first bunch
of them (the number depends on the screen size) in the following format:
     1   Jan 2  Jeroen Stil        (36)   passwd                              
     2   Jan 2  Jos de Bruyne      (32)   WWW
     3   Jan 2  Harm Habing        (112)  morgen, koffie (fwd)
     4   Jan 2  Kees Dullemond     (23)   Adres modificatie
     5   Jan 2  Malcolm Bremer     (48)   Happy New Year!!!
The first number is the sequence number in the folder (according to the current
sorting criterion). Then comes the date, the sender (usually the full name,
unless this is not available, in which case the e-mail address is shown), the
number of lines in the message and the subject.
The current message will be displayed in inverse video, and this is the message
that most commands will work on.
At the bottom of the screen is the menu:
   You can use any of the following commands by pressing the first character;
 d)elete or u)ndelete mail,  m)ail a message,  r)eply or f)orward mail,  q)uit
    To read a message, press [return].  j = move down, k = move up, ? = help
This lists just a subset of the available options.
If you set it to "Expert", you'll get to see a lot more options:
        |=pipe, !=shell, ?=help, [n]=set current to n, /=search pattern
 a)lias, C)opy, c)hange folder, d)elete, e)dit, f)orward, g)roup reply, m)ail,
   n)ext, o)ptions, p)rint, q)uit, r)eply, s)ave, t)ag, u)ndelete, or e(x)it
The system-wide aliases are described in a separate document.
