    Command:

    lesskey

    
    
    

    SYNOPSIS

           lesskey [-o output] [--] [input]
           lesskey [--output=output] [--] [input]
           lesskey -V
           lesskey --version
    
    
    

    DESCRIPTION

           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 speci-
           fied, 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  systems
           $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 version 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 section starts
           with a line that identifies the type  of  section.   Possible  sections
           are:
    
           #command
                  Defines new command keys.
    
           #line-edit
                  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.
    
    
    

    COMMAND SECTION

           The command section begins with the line
    
           #command
    
           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>
    
           \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 performed, 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 example, 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.
    
    
    

    EXAMPLE

           The following input file describes the set of default command keys used
           by less:

                ZZ        quit
    
    
    

    PRECEDENCE

           Commands specified by lesskey take precedence  over  the  default  com-
           mands.   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:
    
           #stop
    
           This  will  cause  all  default commands to be ignored.  The #stop line
           should be the last line in that section of the file.
    
           Be aware that #stop can be dangerous.  Since all default  commands  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 frustration.
    
    
    

    LINE EDITING SECTION

           The line-editing section begins with the line:
    
           #line-edit
    
           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.
    
                \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
    
    
    

    LESS ENVIRONMENT VARIABLES

           The environment variable section begins with the line
    
           #env
    
           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
           system environment and also in a lesskey file, the value in the lesskey
           file  takes precedence.  Although the lesskey file can be used to over-
           ride 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.
    
    
    

    EXAMPLE

           The following input file sets the -i option whenever less is  run,  and
           specifies the character set to be "latin1":
    
                #env
                LESS = -i
                LESSCHARSET = latin1
