       JOE  is a powerful ASCII-text screen editor.  It has a "mode-less" user interface which is
       similar to many user-friendly PC editors.  Users  of  Micro-Pro's  WordStar  or  Borland's
       "Turbo"  languages  will  feel at home.  JOE is a full featured UNIX screen-editor though,
       and has many features for editing programs and text.

       JOE also emulates several other editors.  JSTAR is a close imitation of WordStar with many
       "JOE"  extensions.   JPICO  is a close imitation of the Pine mailing system's PICO editor,
       but with many extensions and improvements.  JMACS is a GNU-EMACS  imitation.   RJOE  is  a
       restricted  version  of  JOE,  which  allows  you  to edit only the files specified on the
       command line.

       Although JOE is actually six different editors, it still requires only one executable, but
       one with six different names.  The name of the editor with an "rc" appended gives the name
       of JOE's initialisation file, which determines the personality of the editor.

       To  start  the  editor, type joe followed by zero or more names of files you want to edit.
       Each file name may be preceded by a local option setting  (see  the  local  options  table
       which  follows).   Other global options, which apply to the editor as a whole, may also be
       placed on the command line (see the global options  table  which  follows).   If  you  are
       editing  a  new  file,  you  can  either give the name of the new file when you invoke the
       editor, or in the editor when you save the new file.  A modified syntax for file names  is
       provided  to allow you to edit program output, standard input/output, or sections of files
       or devices.  See the section Filenames below for details.

       On cygwin32 systems, the special option -CYGhack is replaced by anything that  comes  past
       it  (and separating whitespace) on the command line as one option (to work around a Cygwin
       bug as it cannot correctly be passed a UNC pathname  with  spaces  as  one  argument  from
       Explorer at all).

       Once  you  are  in  the  editor,  you  can  type in text and use special control-character
       sequences to perform  other  editing  tasks.   To  find  out  what  the  control-character
       sequences are, read the rest of this man page or type ^K H for help in the editor.

       Now for some obscure computer-lore:

       The  ^ means that you hold down the Control key while pressing the following key (the same
       way the Shift key works for uppercase letters).  A number  of  control-key  sequences  are
       duplicated  on  other keys, so that you don't need to press the control key: ESC will work
       in place of ^[, Del will work in place of ^?, Backspace will work in place of ^H, Tab will
       work  in  place  of ^I, Return or Enter will work in place of ^M and Linefeed will work in
       place of ^J.  Some keyboards may give you trouble with some control keys.  ^_, ^^  and  ^@
       can  usually be entered without pressing shift (I.E., try ^-, ^6 and ^2).  Other keyboards
       may reassign these to other keys.  Try: ^., ^, and ^/.  ^SPACE  can  usually  be  used  in
       place  of  ^@.  ^\ and ^] are interpreted by many communication programs, including telnet
       and kermit.  Usually  you  just  hit  the  key  twice  to  get  it  to  pass  through  the
       communication program.

       Once you have typed ^K H, the first help window appears at the top of the screen.  You can
       continue to enter and edit text while the help  window  is  on.   To  page  through  other
       topics, hit ^[, and ^[. (that is, ESC , and ESC .).  Use ^K H to dismiss the help window.

       You  can customise the keyboard layout, the help screens and a number of behavior defaults
       by copying JOE's initialisation file (usually /etc/jupp/joerc)  to  .joerc  in  your  home
       directory  and  then  by  modifying  it.   See  the  section joerc below.  The filename is
       actually .namerc where name is the argv[0] the editor is called with.

       Custom syntax files are loaded from  .jupp/syntax/name.jsf  in  your  home  directory  and
       .jupp/charmaps/name  holds  custom  charmaps  (name  here  is  the  name  of the syntax or

       To have JOE used as your default editor for e-mail and News, you need to  set  the  EDITOR
       and VISUAL environment variables in your shell initialisation file (.cshrc or .profile) to
       refer to JOE (the joe binary usually resides as /usr/bin/joe).

       There are a number of other obscure invocation  parameters  which  may  have  to  be  set,
       particularly  if  your  terminal  screen  is not updating as you think it should.  See the
       section Environment variables below.

Command Line Options

       The following global options may be specified on the command line:

       -asis  Characters with codes above 127 will be sent to the terminal as-is, instead  of  as
              inverse  of  the  corresponding  character below 128.  If this does not work, check
              your terminal server.

       -backpath path
              If this option is given, backup files will be stored  in  the  specified  directory
              instead of in each file's original directory.

       -baud nnn
              Set  the  baud  rate for the purposes of terminal screen optimisation.  Joe inserts
              delays for baud rates below 19200, which bypasses tty buffering so  that  typeahead
              will  interrupt  the  screen output.  Scrolling commands will not be used for 38400
              baud.  This is useful for X-terms and other console ttys which really aren't  going
              over a serial line.

       -beep  Joe will beep on command errors and when the cursor goes past extremes.

       -columns nnn
              Sets the number of screen columns.

              Continued  search  mode:  a  search  immediately following a search will repeat the
              previous search instead of prompting for new string.  This is useful  for  the  the
              ^[S and ^[R commands and for when joe is trying to be emacs.

              Joe usually assumes that there is some kind of flow control between it and the tty.
              If there isn't, this option will make joe output extra ^@s to the tty as  specified
              by  the  termcap  entry.   The  extra ^@s allow the terminal to catch up after long
              terminal commands.

       -exask This option makes ^KX verify the file name that it's about to write.

       -force This option makes sure that the last line of the file has a  line-feed  which  it's

       -help  The editor will start with the help screen on if this option is given.

              Normally the column number and control-key prefix fields of the status lines are on
              a one second delay to reduce CPU consumption, but with this option they are updated
              after each key-stroke.

              The  block  highlighting  will  go  away  after any block command if this option is

       -lines nnn
              Sets the number of screen lines.

              Text between ^KB and the cursor is highlighted (use with -lightoff and  a  modified
              joerc file to have drop-anchor style block selection).

       -mid   If  this  option  is  set  and  the cursor moves off the window, the window will be
              scrolled so that the cursor is in the  center.   This  option  is  forced  on  slow
              terminals which don't have scrolling commands.

              This option prevents backup files.

              This  option  prevent  the  copyright  notice  from being displayed when the editor

       -nosta This option eliminates the top-most status line.  It's nice for when you only  want
              to see your text on the screen or if you're using a vt52.

       -noxon Attempt  to turn off ^S/^Q processing.  This is useful for when joe is trying to be
              WordStar or EMACS.

              When this option is active, extra files on the  command  line  will  be  placed  in
              orphaned  buffers  instead  of  in  extra  windows.  This is useful for when joe is
              trying to be emacs.

       -pg nnn
              This specifies the number of lines to keep  after  PgUp/PgDn  (^U/^V).   If  -1  is
              given, half the window is kept.

       -skiptop nnn
              Don't  use  the  top nnn lines of the screen.  Useful for when joe is used as a BBS

       Each of these options may be specified in the joerc file as well.  In addition, the NOXON,
       BAUD,  LINES,  COLUMNS  and DOPADDING options may be specified with environment variables.
       See the section Environment variables below.

       The following options may be specified before each filename on the command line:

       +nnn   The cursor starts on the specified line.

       -crlf  Joe uses CR-LF as the end of line sequence instead of just LF.  This is for editing
              MS-DOS or VMS files.

       -hex   Sets the buffer to hex edit mode.

              Joe wraps the previous word when you type past the right margin.

              When you hit Return on an indented line, the indentation is duplicated onto the new

              Typing overwrites existing characters instead of inserting before them.

       -lmargin nnn
              Sets the left margin.

       -rmargin nnn
              Sets the right margin.

       -tab nnn
              Sets the tab width.

       -indentc nnn
              Sets the indentation character for ^K, and ^K. (32 for SPACE, 9 for TAB).

       -istep nnn
              Sets the indentation step for ^K, and ^K..

              Line numbers are displayed before each line.

              The file is read only.

       -keymap name
              Use an alternate section of the joerc file for  the  key  sequence  bindings.   For
              example, joe, jstar, rjoe and jupp support -keymap cua to make ^Z, ^X, ^C and ^V do
              the same thing as in contemporary GUI editors.

       These options can also be specified in the joerc file.  They can be set depending  on  the
       file-name  extension.   Programs (.c, .h or .p extension) usually have autoindent enabled.
       Wordwrap is enabled on other files, but rc files have it disabled.

Editing Tasks

   Basic Editing
       When you type characters into the editor, they are normally inserted into the  file  being
       edited  (or  appended  to  the file if the cursor is at the end of the file).  This is the
       normal operating mode of the editor.  If you want to replace some existing text, you  have
       to  delete  the  old text before or after you type in the replacement text.  The Backspace
       key can be used for deleting text: move the cursor to right after the  text  you  want  to
       delete and hit Backspace a number of times.

       Hit the Enter or Return key to insert a line-break.  For example, if the cursor was in the
       middle of a line and you hit Return, the line would be  split  into  two  lines  with  the
       cursor appearing at the beginning of the second line.  Hit Backspace at the beginning of a
       line to eliminate a line-break.

       Use the arrow keys to move around the file.  If your keyboard doesn't have arrow keys  (or
       if they don't work for some reason), use ^F to move forwards (right), ^B to move backwards
       (left), ^P to move to the previous line (up), and ^N to move to the next line (down).  The
       right  and  left  arrow  keys  simply  move  forwards or backwards one character at a time
       through the text: if you're at the beginning of a line and you press left-arrow, you  will
       end  up  at  the  end  of the previous line.  The up and down arrow keys move forwards and
       backwards by enough characters so that the cursor appears in the same column that  it  was
       in on the original line.

       If you want to indent the text you enter, you can use the TAB key.  This inserts a special
       control character which makes the characters which follow it begin at the next  TAB  STOP.
       TAB  STOPS  normally occur every 8 columns, but this can be changed with the ^T D command.
       Python programmers often set TAB STOPS on every 4 columns.

       If for some reason your terminal screen gets messed up (for example, if you receive a mail
       notice from biff), you can have the editor refresh the screen by hitting ^R.

       There  are many other keys for deleting text and moving around the file.  For example, hit
       ^D to delete the character the cursor is on instead of deleting backwards like  Backspace.
       ^D will also delete a line-break if the cursor is at the end of a line.  Type ^Y to delete
       the entire line the cursor is on or ^J to delete just from the cursor to the  end  of  the

       Hit ^A to move the cursor to the beginning of the line it's on.  Hit ^E to move the cursor
       to the end of the line.  Hit ^U or ^V for scrolling the cursor up or down 1/2  a  screen's
       worth.   "Scrolling"  means that the text on the screen moves, but the cursor stays at the
       same place relative to the screen.  Hit ^K U or ^K V to move the cursor to  the  beginning
       or  the  end of the file.  Look at the help screens in the editor to find even more delete
       and movement commands.

       If you make a mistake, you can hit ^_ to "undo" it.  On most keyboards you hit just ^-  to
       get  ^_,  but  on  some you might have to hold both the Shift and Control keys down at the
       same time to get it.  If you "undo" too  much,  you  can  "redo"  the  changes  back  into
       existence by hitting ^^ (type this with just ^6 on most keyboards).

       If  you were editing in one place within the file, and you then temporarily had to look or
       edit some other place within the file, you can get back to the original place  by  hitting
       ^K  -.  This command actually returns you to the last place you made a change in the file.
       You can step through a history of places with ^K - and ^K =, in the same way you can  step
       through the history of changes with the "undo" and "redo" commands.

       When you are done editing the file, hit ^K X to exit the editor.  You will be prompted for
       a file name if you hadn't already named the file you were editing.

       When you edit a file, you actually edit only a copy of the file.  So if  you  decide  that
       you  don't  want  the changes you made to a file during a particular edit session, you can
       hit ^C to exit the editor without saving them.

       If you edit a file and save the changes, a "backup" copy of that file is  created  in  the
       current  directory,  with a ~ appended to the name, which contains the original version of
       the file.

   Word wrap and formatting
       If you type past the right edge of the screen in a C language or PASCAL file,  the  screen
       will  scroll  to  the  right to follow the cursor.  If you type past the right edge of the
       screen in a normal file  (one  whose  name  doesn't  end  in  .c,  .h  or  .p),  JOE  will
       automatically  wrap the last word onto the next line so that you don't have to hit Return.
       This is called word-wrap mode.  Word-wrap can be turned on or off with the ^T  W  command.
       JOE's  initialisation  file is usually set up so that this mode is automatically turned on
       for all non-program files.  See the section below on the joerc file  to  change  this  and
       other defaults.

       Aside  for  Word-wrap mode, JOE does not automatically keep paragraphs formatted like some
       word-processors.  Instead, if you need a paragraph to be  reformatted,  hit  ^K  J.   This
       command "fills in" the paragraph that the cursor is in, fitting as many words in a line as
       is possible.  A paragraph, in this case, is a block of text separated above and below by a
       blank line.

       The margins which JOE uses for paragraph formatting and word-wrap can be set with the ^T L
       and ^T R commands.  If the left margin is set to a value other than 1, then when you start
       typing at the beginning of a line, the cursor will immediately jump to the left margin.

       If you want to center a line within the margins, use the ^K A command.

   Over-type mode
       Sometimes  it's  tiresome  to have to delete old text before or after you insert new text.
       This happens, for example, when you are changing a table and  you  want  to  maintain  the
       column  position of the right side of the table.  When this occurs, you can put the editor
       in over-type mode with ^T T.  When the editor is in this mode, the characters you type  in
       replace  existing  characters,  in the way an idealised typewriter would.  Also, Backspace
       simply moves left instead of deleting the character to the left, when it's not at the  end
       or  beginning  of  a  line.   Over-type  mode  is not the natural way of dealing with text
       electronically, so you should go back to insert-mode as soon as possible by  typing  ^T  T

       If you need to insert while you're in over-type mode, hit ^@.  This inserts a single SPACE
       into the text.

   Control and Meta characters
       Each character is represented by a number.  For example, the number for 'A' is 65 and  the
       number  for  '1'  is 49.  All of the characters which you normally see have numbers in the
       range of 32 - 126 (this particular arbitrary assignment between characters and numbers  is
       called the ASCII character set).  The numbers outside of this range, from 0 to 255, aren't
       usually displayed, but sometimes have other special meanings.  The number 10, for example,
       is  used  for  the  line-breaks.   You  can  enter  these  special,  non-displayed control
       characters by first hitting ` and then hitting a character in the range @ A B C ... X Y  Z
       [ ^ ] \ _ to get the number 0 - 31, and ? to get 127.  For example, if you hit ` J, you'll
       insert a line-break character, or if you hit ` I, you'll insert  a  TAB  character  (which
       does  the  same thing the TAB key does).  A useful control character to enter is 12 (` L),
       which causes most printers to advance to the top of the  page.   You'll  notice  that  JOE
       displays  this  character as an underlined L.  You can enter the characters above 127, the
       meta characters, by first hitting ^\.  This  adds  128  to  the  next  (possibly  control)
       character  entered.   JOE  displays  characters  above 128 in inverse-video.  Some foreign
       languages, which have more letters than English, use the meta characters for the  rest  of
       their  alphabet.   You have to put the editor in ASIS mode (described later) to have these
       passed untranslated to the terminal.

       If you hit TAB at any file name prompt, joe will attempt to complete the name you  entered
       as much as possible.  If it couldn't complete the entire name, because there are more than
       one possible completions, joe beeps.  If you hit TAB again, joe list the completions.  You
       can  use  the  arrow  keys to move around this directory menu and press RETURN or SPACE to
       select an item.  If you press the first letter of one of the directory entries, it will be
       selected,  or  if  more  than  one  entry  has the same first letter, the cursor will jump
       between those entries.  If you select a subdirectory or .., the directory name is appended
       to  the prompt and the new directory is loaded into the menu.  You can hit Backspace to go
       back to the previous directory.

       Most prompts record a history of the responses you give them.  You can  hit  up  and  down
       arrow to step through these histories.

       Prompts  are  actually single line windows with no status line, so you can use any editing
       command that you normally use on text within the prompts.  The prompt history is  actually
       just  other lines of the same "prompt file".  Thus you can can search backwards though the
       prompt history with the normal ^K F command if you want.

       Since prompts are windows, you can also switch out of them with ^K P and ^K N.

   Where am I?
       Hit ^K SPACE to have JOE report the line number, column number, and  byte  number  on  the
       last  line  of the screen.  The number associated with the character the cursor is on (its
       ASCII code) is also shown.  You can have the  line  number  and/or  column  number  always
       displayed  on  the  status line by setting placing the appropriate escape sequences in the
       status line setup strings.  Edit the joerc file for details.

   File operations
       You can hit ^K D to save the current file (possibly under a different name from  what  the
       file  was  called  originally).   After  the  file  is  saved,  you can hit ^K E to edit a
       different file.

       If you want to save only a selected section of the file, see the section on Blocks below.

       If you want to include another file in the file you're editing, use ^K R to insert it.

   Temporarily suspending the editor
       If you need to temporarily stop the editor and go back to the shell, hit ^K Z.  You  might
       want  to do this to stop whatever you're editing and answer an e-mail message or read this
       man page, for example.  You have to type fg or exit (you'll be told which when you hit  ^K
       Z) to return to the editor.

   Searching for text
       Hit  ^K F to have the editor search forwards or backwards for a text fragment (string) for
       you.  You will be prompted for the text to search for.  After  you  hit  Return,  you  are
       prompted  to  enter options.  You can just hit Return again to have the editor immediately
       search forwards for the text, or you can enter one or more of these options:

       b      Search backwards instead of forwards.

       i      Treat uppercase and lower case  letters  as  the  same  when  searching.   Normally
              uppercase and lowercase letters are considered to be different.

       nnn    (where  nnn is a number) If you enter a number, JOE searches for the Nth occurrence
              of the text.  This is useful for going to specific places in  files  structured  in
              some regular manner.

       r      Replace  text.   If  you  enter the r option, then you will be further prompted for
              replacement text.  Each time the editor finds the search text, you will be prompted
              as  to whether you want to replace the found search text with the replacement text.
              You hit: y to replace the text and then find the next occurrence, n to not  replace
              this  text,  but  to  then find the next occurrence, l to replace the text and then
              stop searching, r to replace all of the remaining occurrences of the search text in
              the  remainder  of  the  file  without  asking for confirmation (subject to the nnn
              option above), or ^C to stop searching and replacing.

       You can hit ^L to repeat the previous search.

   Regular Expressions
       A number of special character sequences may be entered as search text:

       \*     This finds zero or more characters.  For example, if you give A\*B  as  the  search
              text, JOE will try to find an A followed by any number of characters and then a B.

       \?     This  finds  exactly  one  character.   For example, if you give A\?B as the search
              text, JOE will find AXB, but not AB or AXXB.

       \^ \$  These match the beginning and end of a line.  For example, if  you  give  \^test\$,
              then JOE with find test on a line by itself.

       \< \>  These  match the beginning and end of a word.  For example, if you give \<\*is\*\>,
              then joe will find whole words which have the sub-string is within them.

       \[...] This matches any single character which appears within the brackets.  For  example,
              if  \[Tt]his  is  entered  as the search string, then JOE finds both This and this.
              Ranges of characters can be entered within the brackets.  For example, \[A-Z] finds
              any  uppercase letter.  If the first character given in the brackets is ^, then JOE
              tries to find any character not given in the the brackets.

       \c     This works like \*, but matches a balanced C-language expression.  For example,  if
              you search for malloc(\c), then JOE will find all function calls to malloc, even if
              there was a ) within the parenthesis.

       \+     This finds zero or more of the character which immediately  follows  the  \+.   For
              example,  if you give \[ ]\+\[ ], where the characters within the brackets are both
              SPACE and TAB, then JOE will find whitespace.

       \\     Matches a single \.

       \n     This finds the special end-of-line or line-break character.

       A number of special character sequences may also be given in the replacement string:

       \&     This gets replaced by the text which matched the search string.   For  example,  if
              the search string was \<\*\>, which matches words, and you give "\&", then joe will
              put quote marks around words.

       \0 - \9
              These get replaced with the text which matched the Nth  \*,  \?,  \+,  \c,  \+,  or
              \[...] in the search string.

       \\     Use this if you need to put a \ in the replacement string.

       \n     Use this if you need to put a line-break in the replacement string.

       Some examples:

       Suppose  you  have  a  list  of  addresses,  each  on  a  separate line, which starts with
       "Address:" and has each element separated by commas.  Like so:

       Address: S. Holmes, 221b Baker St., London, England

       If you wanted to rearrange the list, to get the country first, then  the  city,  then  the
       person's name, and then the address, you could do this:

       Type ^K F to start the search, and type:


       to  match  "Address:",  the  four  comma-separated elements, and then the end of the line.
       When asked for options, you would type r to replace the string, and then type:


       To shuffle the information the way you want it. After hitting  return,  the  search  would
       begin, and the sample line would be changed to:

       Address: England, London, S. Holmes, 221b Baker St.

       If  you  want to move, copy, save or delete a specific section of text, you can do it with
       highlighted blocks.  First, move the cursor to the start of the section of text  you  want
       to  work  on, and press ^K B.  Then move the cursor to the character just after the end of
       the text you want to affect and press ^K K.  The text between the ^K B  and  ^K  K  should
       become  highlighted.   Now you can move your cursor to someplace else in your document and
       press ^K M to move the highlighted text there.  You can press ^K C to make a copy  of  the
       highlighted  text  and  insert  it to where the cursor is positioned.  ^K Y to deletes the
       highlighted text.  ^K W, writes the highlighted text to a file.

       A very useful command is ^K /, which filters a block of text through a unix command.   For
       example,  if  you  select a list of words with ^K B and ^K K, and then type ^K / sort, the
       list of words will be sorted.  Another useful unix command for ^K /, is tr.  If  you  type
       ^K  /  tr  a-z  A-Z, then all of the letters in the highlighted block will be converted to

       After you are finished with some block operations, you can just leave the highlighting  on
       if you don't mind it (of course, if you accidentally hit ^K Y without noticing...).  If it
       really bothers you, however, just hit ^K B ^K K, to turn the highlighting off.

   Indenting program blocks
       Auto-indent mode toggled with the ^T I command.  The joerc is  normally  set  up  so  that
       files with names ending with .p, .c or .h have auto-indent mode enabled.  When auto-indent
       mode is enabled and you hit Return, the cursor will be placed in the same column that  the
       first non-SPACE/TAB character was in on the original line.

       You  can use the ^K , and ^K . commands to shift a block of text to the left or right.  If
       no highlighting is set when you give these commands,  the  program  block  the  cursor  is
       located  in will be selected, and will be moved by subsequent ^K , and ^K . commands.  The
       number of columns these commands shift by can be set through a ^T option.

       You can edit more than one file at the same time or edit two or more different  places  of
       the  same  file.  To do this, hit ^K O, to split the screen into two windows.  Use ^K P or
       ^K N to move the cursor into the top window or the lower window.  Use ^K E to edit  a  new
       file  in  one  of  the windows.  A window will go away when you save the file with ^K X or
       abort the file with ^C.  If you abort a file which exists  in  two  windows,  one  of  the
       window goes away, not the file.

       You  can  hit  ^K  O  within  a  window to create even more windows.  If you have too many
       windows on the screen, but you don't want to eliminate them, you can hit ^K I.  This  will
       show  only  the  window the cursor is in, or if there was only one window on the screen to
       begin with, try to fit all hidden windows on the screen.  If there are more  windows  than
       can  fit on the screen, you can hit ^K N on the bottom-most window or ^K P on the top-most
       window to get to them.

       If you gave more than one file name to JOE on the command line, each file will  be  placed
       in a different window.

       You can change the height of the windows with the ^K G and ^K T commands.

   Keyboard macros
       Macros  allow  you  to record a series of keystrokes and replay them with the press of two
       keys.  This is useful to automate repetitive tasks.  To start a macro recording, hit ^K  [
       followed  by  a  number from 0 to 9.  The status line will display (Macro n recording...).
       Now, type in the series of keystrokes that you want to be able to  repeat.   The  commands
       you  type  will  have  their  usual  effect. Hit ^K ] to stop recording the macro.  Hit ^K
       followed by the number you recorded the macro in to execute  one  iteration  of  the  key-

       For example, if you want to put "**" in front of a number of lines, you can type:

       ^K [ ^A ** <down arrow> ^K ]

       Which  starts  the macro recording, moves the cursor to the beginning of the line, inserts
       "**", moves the cursor down one line, and then ends the recording. Since we  included  the
       key-strokes  needed  to  position  the cursor on the next line, we can repeatedly use this
       macro without having to move the cursor ourselves, something you  should  always  keep  in
       mind when recording a macro.

       If  you  find that the macro you are recording itself has a repeated set of key-strokes in
       it, you can record a macro within the macro, as long as you use a different macro  number.
       Also you can execute previously recorded macros from within new macros.

       You can use the repeat command, ^K \, to repeat a macro, or any other edit command or even
       a normal character, a specified number of times.  Hit ^K \, type in the  number  of  times
       you  want  the command repeated and press Return.  The next edit command you now give will
       be repeated that many times.

       For example, to delete the next 20 lines of text, type:

       ^K  20<return>^Y

   Rectangle mode
       Type ^T X to have ^K B and ^K  K  select  rectangular  blocks  instead  of  stream-of-text
       blocks.  This mode is useful for moving, copying, deleting or saving columns of text.  You
       can also filter columns of text with the ^K / command- if you want to sort a  column,  for
       example.  The insert file command, ^K R is also effected.

       When  rectangle  mode  is  selected, over-type mode is also useful (^T T).  When over-type
       mode is selected, rectangles will replace existing text instead of getting inserted before
       it.   Also  the  delete block command (^K Y) will clear the selected rectangle with SPACEs
       and TABs instead of deleting it.  Over-type mode is especially useful for the filter block
       command (^K /), since it will maintain the original width of the selected column.

   Tag search
       If you are editing a large C program with many source files, you can use the ctags program
       to generate a tags file.  This file contains a list of program symbols and the  files  and
       positions  where the symbols are defined.  The ^K ; command can be used to lookup a symbol
       (functions, defined constants, etc.), load the file where the symbol is defined  into  the
       current  window  and position the cursor to where the symbol is defined.  ^K ; prompts you
       for the symbol you want, but uses the symbol the cursor was on as a default.  Since  ^K  ;
       loads  the  definition file into the current window, you probably want to split the window
       first with ^K O, to have both the original file and the definition file loaded.

   Shell windows
       Hit ^K ' to run a command shell in one of JOE's windows.  When the cursor is at the end of
       a shell window (use ^K V if it's not), whatever you type is passed to the shell instead of
       the window.  Any output from the shell or from commands executed in the shell is  appended
       to  the  shell  window (the cursor will follow this output if it's at the end of the shell
       window).  This command is useful for recording the results of shell commands- for  example
       the  output  of  make,  the  result  of grepping a set of files for a string, or directory
       listings from FTP sessions.  Besides typeable characters, the  keys  ^C,  Backspace,  DEL,
       Return  and  ^D  are  passed  to the shell.  Type the shell exit command to stop recording
       shell output.  If you press ^C in a shell window, when the cursor is not at the end of the
       window, the shell is killed.

Environment variables

       For JOE to operate correctly, a number of other environment settings must be correct.  The
       throughput (baud rate) of the connection between the computer and your  terminal  must  be
       set  correctly  for  JOE  to  update  the screen smoothly and allow typeahead to defer the
       screen update.  Use the stty nnn command to set this.  You want to  set  it  as  close  as
       possible  to actual throughput of the connection.  For example, if you are connected via a
       1200 baud modem, you want to use this value for stty.  If  you  are  connected  via  14.4k
       modem,  but the terminal server you are connected to connects to the computer a 9600 baud,
       you want to set your speed as 9600 baud.  The special baud rate of 38400 or extb  is  used
       to indicate that you have a very-high speed connection, such as a memory mapped console or
       an X-window terminal emulator.  If you  can't  use  stty  to  set  the  actual  throughput
       (perhaps  because of a modem communicating with the computer at a different rate than it's
       communicating over the phone line), you can put a numeric value in  the  BAUD  environment
       variable instead (use setenv BAUD 9600 for csh or BAUD=9600; export BAUD for sh).

       The  SHELL  or  EXECSHELL environment variable must be set to the full pathname of a shell
       executable that accepts the -i (interactive) and -c (run a command) arguments of the  Korn
       Shell; otherwise, /bin/sh is used.

       The  TERM  environment  variable must be set to the type of terminal you're using.  If the
       size (number of lines/columns) of your terminal is different from what is reported in  the
       TERMCAP  or  TERMINFO entry, you can set this with the stty rows nn cols nn command, or by
       setting the LINES and COLUMNS environment variables.

       The xterm-xfree86 terminal allows automatic entering and leaving of  the  bracketed  paste

       The  JOETERM  environment  variable  may  be  set to override the regular TERM environment
       variable for specifying your terminal type.

       JOE uses two character maps for its operation:  the  terminal  I/O  character  map,  which
       determines  how  characters  are  sent  to  the  terminal  and  whether  the %a/%A message
       specifiers use UCS, and the file encoding, which can  be  specified  per  file  using  the
       -encoding option and changed with the ^T E command, and which defaults to the terminal I/O
       character map, which, in turn, is determined  from  the  current  locale,  if  the  system
       supports  such,  otherwise  the  LC_ALL,  LC_CTYPE and LANG environment variables (if they
       contain a period, only the part after it and before an optional "at  sign"  is  used);  on
       cygwin32  before  1.7.2,  the  codepage  is  used  instead if the POSIX locale environment
       variables are empty; the environment variable JOECHARMAP can be used to manually force one
       overriding all methods described above, and can be used together with -encoding to specify
       a different default file character map.

       JOE normally expects that flow control between the computer and your terminal to use ^S/^Q
       handshaking  (I.E., if the computer is sending characters too fast for your terminal, your
       terminal sends ^S to stop the output and ^Q to restart it).  If the flow control uses out-
       of-band  or hardware handshaking or if your terminal is fast enough to always keep up with
       the computer output and you  wish  to  map  ^S/^Q  to  edit  commands,  you  can  set  the
       environment  variable  NOXON  to  have  JOE attempt to turn off ^S/^Q handshaking.  If the
       connection between the computer and your terminal uses no handshaking and your terminal is
       not  fast  enough  to keep up with the output of the computer, you can set the environment
       variable DOPADDING to have JOE slow  down  the  output  by  interspersing  PAD  characters
       between the terminal screen update sequences.


       Wherever  JOE  expects you to enter a file name, whether on the command line or in prompts
       within the editor, you may also type:

              Read or write data to or from a shell command.  For example, use joe '!ls' to get a
              copy  of  your  directory  listing to edit or from within the editor use ^K D !mail
     to send the file being edited to me.

              Use this to have JOE append the edited text to the end of the file "filename."

              Use this to access a fixed section of a file or device.   START  and  SIZE  may  be
              entered  in  decimal  (ex.: 123) octal (ex.: 0777) or hexadecimal (ex.: 0xFF).  For
              example, use joe /dev/fd0,508,2 to edit bytes 508 and 509 of the first floppy drive
              in Linux.

       -      Use  this  to  get input from the standard input or to write output to the standard
              output.  For example, you can put joe in a pipe of commands: quota -v  |  joe  -  |
              mail root, if you want to complain about your low quota.

The joerc file

       ^T  options,  the  help  screens  and  the key-sequence to editor command bindings are all
       defined in JOE's initialisation file.  If you make a copy of  this  file  (which  normally
       resides  in  /etc/jupp/joerc)  to  $HOME/.joerc,  you can customise these settings to your
       liking.  The syntax of the initialisation file should be fairly  obvious,  and  there  are
       further instruction in it.
