LLLLEEEESSSSSSSSKKKKEEEEYYYY((((1111)))) UUUUNNNNIIIIXXXX 5555....0000 LLLLEEEESSSSSSSSKKKKEEEEYYYY((((1111)))) NNNNAAAAMMMMEEEE lesskey - specify key bindings for less SSSSYYYYNNNNOOOOPPPPSSSSIIIISSSS lllleeeesssssssskkkkeeeeyyyy [[[[----oooo oooouuuuttttppppuuuutttt]]]] [[[[iiiinnnnppppuuuutttt]]]] DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN _L_e_s_s_k_e_y is used to specify a set of key bindings to be used by _l_e_s_s. The input file is a text file which describes the key bindings, and the output file is a binary file which is used by _l_e_s_s. If no input file is specified, standard input is used. If no output file is specified, $HOME/.less is used. The input file 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 carat to indicate a control key. A backslash may be used to cause the following character to be taken literally. Characters which must be preceded by backslash include carat, space, tab and the backslash itself. A backslash followed by one to three octal digits may be used to specify a character by its octal value. Blank lines and lines which start with a pound sign (#) are ignored. An action may be followed by an extra string. This string is parsed after the command is entered, just as if it were entered on the command line. This feature can be used in certain cases to extend the functionality of a command. For example, these entries would create a pair of commands to turn on/off line numbers using _v_i syntax: :set\ nu toggle-option -N :set\ nonu toggle-option +N See also the ":ta" command in the example below.
