mh-e: Ranges

 
 4.2 Ranges
 ==========
 
 Many commands that operate on individual messages, such as ‘mh-forward’
 or ‘mh-refile-msg’ take a ‘RANGE’ argument.  This argument can be used
 in several ways.
 
    If you provide the prefix argument ‘C-u’ to these commands, then you
 will be prompted for the message range.  This can be any valid MH range
 which can include messages, sequences (Sequences), and the
 abbreviations (described in the ‘mh’(1) man page):
 
 ‘<num1>-<num2>’
      Indicates all messages in the range <num1> to <num2>, inclusive.
      The range must be nonempty.
 ‘<num>:N’
 ‘<num>:+N’
 ‘<num>:-N’
      Up to N messages beginning with (or ending with) message num.  Num
      may be any of the predefined symbols: first, prev, cur, next or
      last.
 ‘first:N’
 ‘prev:N’
 ‘next:N’
 ‘last:N’
      The first, previous, next or last messages, if they exist.
 ‘all’
      All of the messages.
 
    For example, a range that shows all of these things is ‘1 2 3 5-10
 last:5 unseen’.
 
    If the option ‘transient-mark-mode’ is turned on and you set a region
 in the MH-Folder buffer, then the MH-E command will perform the
 operation on all messages in that region.
 
    The ‘mh-range’ customization group contains a single option which
 affects how ranges are interpreted.
 
 ‘mh-interpret-number-as-range-flag’
      On means interpret a number as a range (default: ‘on’).
 
    Since one of the most frequent ranges used is ‘last:N’, MH-E will
 interpret input such as ‘200’ as ‘last:200’ if the
 ‘mh-interpret-number-as-range-flag’ option is on (which is the default).
 If you need to scan just the message 200, then use the range ‘200:1’ or
 ‘200-200’.
