         lesskey - specify key bindings for less
         lesskey [-o output] [--] [input]
         lesskey [--output=output] [--] [input]
         lesskey -V
         lesskey --version
         Lesskey is used to specify a set of key bindings to be  used
         by  less.  The input file is a text file which describes the
         key bindings, If the input file is "-",  standard  input  is
         read.  If no input file is specified, a standard filename is
         used as the name of the input file,  which  depends  on  the
         system being used:  On Unix systems, $HOME/.lesskey is used;
         on MS-DOS systems, $HOME/_lesskey is used; and on OS/2  sys-
         tems  $HOME/lesskey.ini  is  used,  or  $INIT/lesskey.ini if
         $HOME is undefined.  The output file is a binary file  which
         is  used  by  less.  If no output file is specified, and the
         environment variable LESSKEY is set, the value of LESSKEY is
         used  as the name of the output file.  Otherwise, a standard
         filename is used as the  name  of  the  output  file,  which
         depends on the system being used:  On Unix and OS-9 systems,
         $HOME/.less is used; on MS-DOS systems, $HOME/_less is used;
         and   on   OS/2   systems,   $HOME/less.ini   is   used,  or
         $INIT/less.ini if $HOME is undefined.  If  the  output  file
         already exists, lesskey will overwrite it.
         The -V or --version option causes lesskey to print its  ver-
         sion  number  and  immediately  exit.  If -V or --version is
         present, other options and arguments are ignored.
         The input file consists of one or more sections.  Each  sec-
         tion starts with a line that identifies the type of section.
         Possible sections are:
              Defines new command keys.
              Defines new line-editing keys.
         #env Defines environment variables.
         Blank lines and lines which start with a pound sign (#)  are
         ignored, except for the special section header lines.
         The command section begins with the line
         If the command section is the first  section  in  the  file,
         this  line  may be omitted.  The command section consists of
         lines of the form:
              string <whitespace> action [extra-string] <newline>
         Whitespace is any sequence of  one  or  more  spaces  and/or
         tabs.   The  string  is  the command key(s) which invoke the
         action.  The string may  be  a  single  command  key,  or  a
         sequence  of  up  to 15 keys.  The action is the name of the
         less action, from the list below.   The  characters  in  the
         string  may  appear  literally, or be prefixed by a caret to
         indicate a control key.  A  backslash  followed  by  one  to
         three octal digits may be used to specify a character by its
         octal value.  A backslash  followed  by  certain  characters
         specifies input characters as follows:
         \b   BACKSPACE
         \e   ESCAPE
         \n   NEWLINE
         \r   RETURN
         \t   TAB
         \ku  UP ARROW
         \kd  DOWN ARROW
         \kr  RIGHT ARROW
         \kl  LEFT ARROW
         \kU  PAGE UP
         \kD  PAGE DOWN
         \kh  HOME
         \ke  END
         \kx  DELETE
         A backslash followed by any other character  indicates  that
         character  is  to be taken literally.  Characters which must
         be preceded by backslash include caret, space, tab  and  the
         backslash itself.
         An action may be followed by an "extra" string.  When such a
         command  is  entered  while running less, the action is per-
         formed, and then the extra string is parsed, just as  if  it
         were  typed  in to less. This feature can be used in certain
         cases to extend the functionality of a command.   For  exam-
         ple,  see  the  "{"  and ":t" commands in the example below.
         The extra string  has  a  special  meaning  for  the  "quit"
         action:   when  less  quits,  first  character  of the extra
         string is used as its exit status.
         The following input file describes the set of  default  com-
         mand keys used by less:
              \r        forw-line

         Commands specified  by  lesskey  take  precedence  over  the
         default  commands.  A default command key may be disabled by
         including it in the input file with  the  action  "invalid".
         Alternatively,  a  key may be defined to do nothing by using
         the action "noaction".  "noaction" is similar to  "invalid",
         but  less  will give an error beep for an "invalid" command,
         but not for a "noaction" command.  In addition, ALL  default
         commands  may be disabled by adding this control line to the
         input file:
         This will cause all default commands  to  be  ignored.   The
         #stop  line  should  be the last line in that section of the
         Be aware that #stop can be dangerous. Since all default com-
         mands  are  disabled,  you  must provide sufficient commands
         before the #stop line to enable all necessary actions.   For
         example,  failure  to  provide  a "quit" command can lead to
         The line-editing section begins with the line:
         This section specifies new key bindings for the line editing
         commands,  in  a  manner similar to the way key bindings for
         ordinary commands are specified  in  the  #command  section.
         The  line-editing  section  consists  of  a list of keys and
         actions, one per line as in the example below.
         The following input file describes the set of default  line-
         editing keys used by less:
              \t        forw-complete
              \17       back-complete
              \e\t      back-complete
              ^L        expand
              ^V        literal
              ^A        literal
              \el       right
              \kr       right
              \eh       left
              \kl       left
              \eb       word-left
              \e\kl     word-left
              \ew       word-right
              \e\kr     word-right
              \ei       insert
              \ex       delete
              \kx       delete
              \eX       word-delete
              \ekx      word-delete
              \e\b      word-backspace
              \e0       home
              \kh       home
              \e$       end
              \ke       end
              \ek       up
              \ku       up
              \ej       down
         The environment variable section begins with the line
         Following this  line  is  a  list  of  environment  variable
         assignments.   Each line consists of an environment variable
         name, an equals sign (=) and the value to be assigned to the
         environment  variable.   White  space  before  and after the
         equals sign is ignored.  Variables assigned in this way  are
         visible only to less. If a variable is specified in the sys-
         tem environment and also in a lesskey file, the value in the
         lesskey  file  takes  precedence.  Although the lesskey file
         can be used to override variables set  in  the  environment,
         the  main purpose of assigning variables in the lesskey file
         is simply to have all less configuration information  stored
         in one file.
         The following input file sets the -i option whenever less is
         run, and specifies the character set to be "latin1":
              LESS = -i
              LESSCHARSET = latin1
         It is not possible to specify special keys, such as uparrow,
         in  a  keyboard-independent manner.  The only way to specify
         such keys is to specify the escape sequence which a particu-
         lar keyboard sends when such a keys is pressed.
         On MS-DOS and OS/2 systems, certain keys send a sequence  of
         characters  which  start with a NUL character (0).  This NUL
         character should be represented as \340 in a lesskey file.
