       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.

              Force multibyte mode on. Multibyte mode is usually enabled automatically as needed.

              Force multibyte mode off, even if it was automatically determined that it should be

       -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


       The following environment variables are processed by le:

       HOME   Used for tilde (`~') expansion.

              The  default EOL marker. It can be set to NL (\n), CRNL (\r\n) or CR (\r).  Also it
              can be set to any other 1-2 character string interpreted literally.

              These variables are used by curses library for full-screen output.


              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.
