       pico - simple text editor in the style of the Pine Composer

       pico [ options ] [ file ]

       Pico  is	 a simple, display-oriented text editor based on the Pine mes‐
       sage system composer.  As with Pine, commands are displayed at the bot‐
       tom  of the screen, and context-sensitive help is provided.  As charac‐
       ters are typed they are immediately inserted into the text.

       Editing commands are entered  using  control-key	 combinations.	 As  a
       work-around  for	 communications	 programs that swallow certain control
       characters, you can emulate a control key  by  pressing	ESCAPE	twice,
       followed	 by  the  desired control character, e.g. "ESC ESC c" would be
       equivalent to entering a ctrl-c.	 The editor has five  basic  features:
       paragraph   justification,   searching,	block  cut/paste,  a  spelling
       checker, and a file browser.

       Paragraph justification (or filling) takes place in the paragraph  that
       contains	 the  cursor, or, if the cursor is between lines, in the para‐
       graph immediately below.	 Paragraphs are delimited by blank  lines,  or
       by  lines  beginning  with a space or tab.  Unjustification can be done
       immediately after justification using the control-U key combination.

       String searches are not sensitive to case.  A search begins at the cur‐
       rent  cursor  position  and wraps around the end of the text.  The most
       recent search string is offered as the default in subsequent searches.

       Blocks of text can be moved, copied or deleted with creative use of the
       command	for mark (ctrl-^), delete (ctrl-k) and undelete (ctrl-u).  The
       delete command will remove text between the "mark" and the current cur‐
       sor  position,  and place it in the "cut" buffer.  The undelete command
       effects a "paste" at the current cursor position.

       The spell checker examines all words in the text.  It then  offers,  in
       turn,  each misspelled word for correction while highlighting it in the
       text.  Spell checking can be cancelled  at  any	time.	Alternatively,
       pico  will  substitute for the default spell checking routine a routine
       defined by the SPELL environment	 variable.   The  replacement  routine
       should read standard input and write standard output.

       The  file browser is offered as an option in the "Read File" and "Write
       Out" command prompts.  It is intended to help in searching for specific
       files  and  navigating directory hierarchies.  Filenames with sizes and
       names of directories in the current working directory are presented for
       selection.   The current working directory is displayed on the top line
       of the display while the list of available commands takes up the bottom
       two.   Several  basic  file manipulation functions are supported:  file
       renaming, copying, and deletion.

       More specific help is available in pico's online help.

       +n     Causes pico to be started with the cursor located n  lines  into
	      the file. (Note: no space between "+" sign and number)

       -b     Enable the option to Replace text matches found using the "Where
	      is" command.

       -d     Rebind the "delete" key so the character the  cursor  is	on  is
	      rubbed out rather than the character to its left.

       -e     Enable file name completion.

       -f     Use  function  keys for commands.	 This option supported only in
	      conjunction with UW Enhanced NCSA telnet.

       -h     List valid command line options.

       -j     Enable "Goto" command in the file	 browser.   This  enables  the
	      command  to  permit  explicitly telling pilot which directory to

       -g     Enable "Show Cursor" mode in file browser.  Cause cursor	to  be
	      positioned  before  the  current selection rather than placed at
	      the lower left of the display.

       -k     Causes "Cut Text" command to remove characters from  the	cursor
	      position	to  the	 end of the line rather than remove the entire

       -m     Enable mouse functionality.  This only works when	 pico  is  run
	      from within an X Window System "xterm" window.

       -nn    The -nn option enables new mail notification.  The n argument is
	      optional, and specifies how often, in seconds, your  mailbox  is
	      checked  for  new	 mail.	For example, -n60 causes pico to check
	      for new mail once every minute.  The  default  interval  is  180
	      seconds,	while  the  minimum  allowed  is  30.  (Note: no space
	      between "n" and the number)

       -o dir Sets operating directory.	 Only files within this directory  are
	      accessible.  Likewise, the file browser is limited to the speci‐
	      fied directory subtree.

       -rn    Sets column used to limit the "Justify" command's right margin

       -s speller
	      Specify an alternate program spell to use when spell checking.

       -t     Enable "tool" mode.  Intended for when pico is used as the  edi‐
	      tor within other tools (e.g., Elm, Pnews).  Pico will not prompt
	      for save on exit, and will not  rename  the  buffer  during  the
	      "Write Out" command.

       -v     View the file only, disallowing any editing.

       -w     Disable word wrap (thus allow editing of long lines).

       -x     Disable keymenu at the bottom of the screen.

       -z     Enable ^Z suspension of pico.

       -q     Termcap  or  terminfo  definition for input escape sequences are
	      used in preference to sequences defined by default.  This option
	      is  only	available  if  pico was compiled with the TERMCAP_WINS
	      define turned on.

       Lastly, when a running pico is disconnected (i.e., receives a  SIGHUP),
       pico  will  save	 the  current  work if needed before exiting.  Work is
       saved under the current filename with ".save" appended.	If the current
       work is unnamed, it is saved under the filename "pico.save".

       The  manner  in	which lines longer than the display width are dealt is
       not immediately obvious.	 Lines that continue beyond the	 edge  of  the
       display	are indicated by a '$' character at the end of the line.  Long
       lines are scrolled horizontally as the cursor moves through them.

       pico.save	Unnamed interrupted work saved here.
       *.save		Interrupted work on a named file is saved here.
