       le - full screen text editor


       le [options] filename


       le  is  a  text  editor  which offers wide range of capabilities with a
       simple 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
       rectangular blocks, search and replace with full  regular  expressions,
       text formatting, undelete/uninsert, hex editing, tunable key sequences,
       tunable colors, tunable syntax highlighting.

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


       Here are some starting hints:

       F10 or C-n

       F1     help

       C-x    exit (cancel)

       Arrows navigate

       In the editor the following key description is used:

              simultaneous key1 and key2 press

              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+|
       followed by command name.


       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.


       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
       editor 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.


       -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.

              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.

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

       -c, --color
              Start in color mode

              Dump default keymap to stdout and exit

              Dump default color map to stdout and exit

              Print the version of LE and exit

       --help Print short description of options and exit


              Color palette description. Those files are sequentially read and
              color definitions in later files have higher precision.

              Key map descriptions. Only the first existing file is read.

              Terminal specific options. Only the first existing file is read.
              Use Options->Terminal menu to tune the options.

              Options. Only the first existing file is read. Use menu  Options
              to tune these.

              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.

              Main  editor  menu.  It  has  simple text format. Only the first
              existing file is read.

              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.
