NAME
       le - full screen	text editor

SYNOPSIS
       le [options] filename

DESCRIPTION
       le is a text editor which offers	wide range of capabilities with	a sim-
       ple interface. It has a pull down menu and a simple help	system to  get
       started.	See KEYS section below to learn	about key combinations.

       Among  its  features there are: various operations with stream and rec-
       tangular	blocks,	search and replace with	full regular expressions, text
       formatting, undelete/uninsert, hex editing, tunable key sequences, tun-
       able colors, tunable syntax highlighting.

       The editor currently supports only one loaded file at a time.

KEYS
       Here are	some starting hints:

       F10 or C-n
	      menu

       F1     help

       C-x    exit (cancel)

       Arrows navigate

       In the editor the following key description is used:

       Key1-Key2
	      simultaneous key1	and key2 press

       Key1+Key2
	      sequential keys press

       Key1 | Key2
	      press Key1 OR Key2

       ^Key   Ctrl-Key

       ~Key   Shift-Key

       ^~Key  Ctrl-Shift-Key | Alt-Key

       Some of ^Fx, ~Fx, ^~Fx can be typed as ESC+Fx.

       The rest	of key combinations can	be seen	in help, in menu  and  in  the
       keyboard	map (default one can be	seen with le --dump-keymap).

       There  is  support  for	block filtering	through	an external program, a
       command output read-in, writing a block through a command. To  read  or
       write  block  from/to  a	command, use F4+R or F4+W and file name	of the
       following format: ``|command args''. Filtering is achieved by F4+| fol-
       lowed by	command	name.

STATUS LINE
       On the status line you can see current line, column, the	size of	loaded
       file, the code of character under cursor,  several  one	letter	flags,
       file name, offset in bytes from the file	beginning and percent position
       in the file.

       One letters flags are: *	- modified; R -	Russian	keyboard  (works  only
       on  certain terminals); I - insert, O - overstrike; A - autoindent; D -
       dos style line terminators (CR NL); U - undelete	possible, u - uninsert
       possible; B - column block mode.

TEXT PROTECTION
       To  prevent changes loss	on crash, le regularly dumps the editing text,
       if changed, to ~/.le/tmp/FILENAME.PID , where FILENAME is the file name
       with slashes converted to underlines; PID is the	process	id of the edi-
       tor process.

       When the	editor gets a  fatal  signal,  it  also	 dumps	the  text,  to
       ~/.le/tmp/DUMP-SIG-FILENAME.PID , where SIG is the signal number.

OPTIONS
       -r, --read-only
	      Work  as	viewer,	 don't	allow changes. If your system supports
	      mmap(2), it will be used to get file contents to memory.

       -h, --hex-mode
	      Start in hex mode

       --mmap Use mmap(2) to load file read-only. Can be  used	to  view  very
	      large files or even devices. This	implies	-h.

       --mmap-rw
	      Use mmap(2) to load file read-write in MAP_SHARED	mode. Use with
	      caution -- the changes go	directly to file or disk, no undo.  In
	      this  mode  only	replace	 can be	used, but it allows editing of
	      very large files or even devices.	 This implies -h.

       --multibyte
	      Force multibyte mode on. Multibyte mode is usually enabled auto-
	      matically	as needed.

       --no-multibyte
	      Force  multibyte	mode  off, even	if it was automatically	deter-
	      mined that it should be on.

       -b, --black-white
	      Start in black & white mode

       -c, --color
	      Start in color mode

       --dump-keymap
	      Dump default keymap to stdout and	exit

       --dump-colors
	      Dump default color map to	stdout and exit

       --version
	      Print the	version	of LE and exit

       --help Print short description of options and exit

FILES
       DATADIR/colors
       ~/.le/colors
       DATADIR/colors-$TERM
       ~/.le/colors-$TERM
	      Color palette description. Those files are sequentially read and
	      color definitions	in later files have higher precision.

       ~/.le/keymap-$TERM
       DATADIR/keymap-$TERM
       ~/.le/keymap
       DATADIR/keymap
	      Key map descriptions. Only the first existing file is read.

       ~/.le/term-$TERM
       DATADIR/term-$TERM
	      Terminal specific	options. Only the first	existing file is read.
	      Use Options->Terminal menu to tune the options.

       ./.le.ini
       ~/.le/le.ini
       DATADIR/le.ini
	      Options. Only the	first existing file is read. Use menu  Options
	      to tune these.

       .le.syntax
       ~/.le/syntax
       DATADIR/syntax
	      Syntax  highlighting  rules.   Only  the	first existing file is
	      read. There is no	default	built-in in the	editor,	 so  if	 those
	      files are	not present you	won't see any syntax highlighting.

       ~/.le/mainmenu
       DATADIR/mainmenu
	      Main  editor menu. It has	simple text format. Only the first ex-
	      isting file is read.

       ~/.le/history
	      Various histories	are saved here.	Do not edit by hand.

       DATADIR is determined at	compile	time by	configure  script  (pkgdatadir
       variable). By default it	has value /usr/local/share/le.
