In previous versions of less, a\nseparate program called lesskey was used to compile the lesskey source\nfile into a format understood by less. This compilation step is no\nlonger required and the lesskey program is therefore deprecated al-\nthough the file format remains supported by less itself.\n", "subsections": [] }, "FILE FORMAT": { "content": "The input file consists of one or more sections. Each section starts\nwith a line that identifies the type of section. Possible sections\nare:\n\n#command\nDefines new command keys.\n\n#line-edit\nDefines new line-editing keys.\n\n#env Defines environment variables.\n\nBlank lines and lines which start with a pound sign (#) are ignored,\nexcept for the special section header lines.\n", "subsections": [] }, "COMMAND SECTION": { "content": "The command section begins with the line\n\n#command\n\nIf the command section is the first section in the file, this line may\nbe omitted. The command section consists of lines of the form:\n\nstring action [extra-string] \n\nWhitespace is any sequence of one or more spaces and/or tabs. The\nstring is the command key(s) which invoke the action. The string may\nbe a single command key, or a sequence of up to 15 keys. The action is\nthe name of the less action, from the list below. The characters in\nthe string may appear literally, or be prefixed by a caret to indicate\na control key. A backslash followed by one to three octal digits may\nbe used to specify a character by its octal value. A backslash fol-\nlowed by certain characters specifies input characters as follows:\n\n\\b BACKSPACE\n\n\\e ESCAPE\n\n\\n NEWLINE\n\n\\r RETURN\n\n\\t TAB\n\n\\ku UP ARROW\n\n\\kd DOWN ARROW\n\n\\kr RIGHT ARROW\n\n\\kl LEFT ARROW\n\n\\kU PAGE UP\n\n\\kD PAGE DOWN\n\n\\kh HOME\n\n\\ke END\n\n\\kx DELETE\n\nA backslash followed by any other character indicates that character is\nto be taken literally. Characters which must be preceded by backslash\ninclude caret, space, tab and the backslash itself.\n\nAn action may be followed by an \"extra\" string. When such a command is\nentered while running less, the action is performed, and then the extra\nstring is parsed, just as if it were typed in to less. This feature\ncan be used in certain cases to extend the functionality of a command.\nFor example, see the \"{\" and \":t\" commands in the example below. The\nextra string has a special meaning for the \"quit\" action: when less\nquits, the first character of the extra string is used as its exit sta-\ntus.\n", "subsections": [] }, "EXAMPLE": { "content": "The following input file sets the -i option whenever less is run, and\nspecifies the character set to be \"latin1\":\n\n#env\nLESS = -i\nLESSCHARSET = latin1\n", "subsections": [] }, "PRECEDENCE": { "content": "Commands specified by lesskey take precedence over the default com-\nmands. A default command key may be disabled by including it in the\ninput file with the action \"invalid\". Alternatively, a key may be de-\nfined to do nothing by using the action \"noaction\". \"noaction\" is sim-\nilar to \"invalid\", but less will give an error beep for an \"invalid\"\ncommand, but not for a \"noaction\" command. In addition, ALL default\ncommands may be disabled by adding this control line to the input file:\n\n#stop\n\nThis will cause all default commands to be ignored. The #stop line\nshould be the last line in that section of the file.\n\nBe aware that #stop can be dangerous. Since all default commands are\ndisabled, you must provide sufficient commands before the #stop line to\nenable all necessary actions. For example, failure to provide a \"quit\"\ncommand can lead to frustration.\n", "subsections": [] }, "LINE EDITING SECTION": { "content": "The line-editing section begins with the line:\n\n#line-edit\n\nThis section specifies new key bindings for the line editing commands,\nin a manner similar to the way key bindings for ordinary commands are\nspecified in the #command section.

White space\nbefore and after the equals sign is ignored. Variables assigned in\nthis way are visible only to less. If a variable is specified in the\nsystem environment and also in a lesskey file, the value in the lesskey\nfile takes precedence. Although the lesskey file can be used to over-\nride variables set in the environment, the main purpose of assigning\nvariables in the lesskey file is simply to have all less configuration\ninformation stored in one file.\n", "subsections": [] }, "SEE ALSO": { "content": "less(1)\n", "subsections": [] }, "WARNINGS": { "content": "On MS-DOS and OS/2 systems, certain keys send a sequence of characters\nwhich start with a NUL character (0).
