T)opic scan of messages.  The "T" command reviews just the topic of the
messages.  It lists 3 columns of message numbers beside their topics.  You
can specify criteria for what messages to scan.  The most common useful
options are:

  S (or *) =  forward from where you last read (same as *)
  L        =  read backwards from Last Message
  F        =  read just the mail From you
  T        =  read just the mail To you specifically (or to ALL)
  M        =  your mail specifically addressed to you
  xxxx-    =  backward from message number xxxx
  xxxx+    =  forward from message number xxxx
  <text>   =  only messages with <text> in the subject/to/from fields

TIPS:
1. You can jump to reading the message you want just by typing in the
numbers of the messages at the MORE prompt.

2. The S)can messages commands shows more information about each messages.
