  15.           _L_e_s_s_k_e_y is used to specify a set of key bindings to be used
  16.           by _l_e_s_s. The input file is a text file which describes the
  17.           key bindings, and the output file is a binary file which is
  18.           used by _l_e_s_s. If no input file is specified, standard input
  19.           is used.  If no output file is specified, $HOME/.less is
  20.           used.
  21.  
  22.           The input file consists of lines of the form:
  23.  
  24.                string <whitespace> action [extra-string] <newline>
  25.  
  26.           Whitespace is any sequence of one or more spaces and/or
  27.           tabs.  The "string" is the command key(s) which invoke the
  28.           action.  The string may be a single command key, or a
  29.           sequence of up to 15 keys.  The "action" is the name of the
  30.           less action, from the list below.  The characters in the
  31.           "string" may appear literally, or be prefixed by a carat to
  32.           indicate a control key.  A backslash may be used to cause
  33.           the following character to be taken literally.  Characters
  34.           which must be preceded by backslash include carat, space,
  35.           tab and the backslash itself.  A backslash followed by one
  36.           to three octal digits may be used to specify a character by
  37.           its octal value.  Blank lines and lines which start with a
  38.           pound sign (#) are ignored.
  39.  
  40.           An action may be followed by an extra string.  This string
  41.           is parsed after the command is entered, just as if it were
  42.           entered on the command line.  This feature can be used in
  43.           certain cases to extend the functionality of a command.  For
  44.           example, these entries would create a pair of commands to
  45.           turn on/off line numbers using _v_i syntax:
  46.  
  47.                :set\ nu       toggle-option -N
  48.                :set\ nonu     toggle-option +N
  49.  
  50.           See also the ":ta" command in the example below.
