Name
       pico - simple text editor in the	style of the Alpine Composer

Syntax
       pico [ options ]	[ file ]

Description
       Pico is a simple, display-oriented text editor based on the Alpine mes-
       sage system composer.  As with Alpine, commands are  displayed  at  the
       bottom of the screen, and context-sensitive help	is provided.  As char-
       acters 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.

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

       -a     Display all files	including those	beginning with a period	(.).

       -b     Enable the option	to Replace text	matches	found using the	"Where
	      is" command. This	now  does  nothing.  Instead,  the  option  is
	      always turned on (as if the -b flag had been specified).

       -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
	      visit.

       -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
	      line.

       -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.

       -version
	      Print Pico version and exit.

       -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.

       -p     Preserve the "start" and "stop" characters, typically Ctrl-Q and
	      Ctrl-S, which are	sometimes used in communications paths to con-
	      trol data	flow between devices that operate at different speeds.

       -Q quotestr
	      Set the quote string.  Especially	useful when  composing	email,
	      setting this allows the quote string to be checked for when Jus-
	      tifying paragraphs.  A common quote string is "> ".

       -W word_separators
	      If characters listed here	appear in the middle of	 a  word  sur-
	      rounded  by  alphanumeric	characters that	word is	split into two
	      words. This is used by the Forward and  Backward	word  commands
	      and by the spell checker.

       -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.

       -setlocale_ctype
	      Do setlocale(LC_CTYPE) if	available. Default is to not  do  this
	      setlocale.

       -no_setlocale_collate
	      Do  not  do  setlocale(LC_COLLATE). Default is to	do this	setlo-
	      cale.

       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".

Color Support
       If your terminal	supports colors, Pico can be configured	to color text.
       Users can configure the color of	the text, the text in  the  key	 menu,
       the  titlebar, messages and prompt in the status	line. As an added fea-
       ture Pico can also be used to configure the color of up to  three  dif-
       ferent  levels  of  quoted text,	and the	signature of an	email message.
       This is useful when Pico	is used	as a tool (with	the  -t	 command  line
       switch.)

       Pico  can  tell	you  the number	of colors that your terminal supports,
       when started with the switch -color_codes. In addition Pico will	 print
       a  table	 showing  the  numerical code of every color supported in that
       terminal. In order to configure colors, one must	 use  these  numerical
       codes.  For  example,  0	is for black, so in order to configure a black
       color, one must use its code, the number	0.

       In order	to activate colors, one	must use the option  -ncolors  with  a
       numerical value indicating the number of	colors that your terminal sup-
       ports, for example, -ncolors 256	indicates that the user	wishes to  use
       a table of 256 colors.

       All options that	control	color, are four	letter options.	Their last two
       letters are either "fc" or "bc",	indicating foreground color  and  bac-
       ground  color, respectively. The	first two letters indicate the type of
       text that is being configured, for example "nt" stands for normal text,
       so that -ntfc represents	the color of the normal	text, while -ntbc rep-
       resents the color of the	background of normal text. Here	is a  complete
       list of the color options supported by Pico.

       -color_codes
	      displays	the  number of colors supported	by the terminal, and a
	      table showing the	association of colors and numerical codes

       -ncolors
	      activates	color support in Pico, and tells Pico how many	colors
	      to  use.	 Depending  on your terminal number could be 8,	16, or
	      256.

       -ntfc  specifies	the number num of the color to be used to color	normal
	      text.

       -ntbc  specifies	the number num of the color of the background for nor-
	      mal text.

       -rtfc  number of	the color of reverse text. Default: same as background
	      color of normal text (if specified.)

       -rtbc  number  of the color of the background of	reverse	text. Default:
	      same as color of normal text (if specified.)

       -tbfc  number of	color of text of the title bar.	Default: same as fore-
	      ground color of reverse text.

       -tbbc  number of	the color of background	of the title bar.

       -klfc  number of	the color of the text of the key label.

       -klbc  number of	color of background of the key label.

       -knfc  number of	color of text of the key name.

       -knbc  number of	color of background of the key name.

       -stfc  number of	color of text of the status line.

       -stbc  number of	color of background of the status line.

       -prfc  number of	color of text of a prompt.

       -prbc  number of	color of background of a prompt.

       -q1fc  number of	color of text of level one of quoted text.

       -q1bc  number  of  color	 of background of level	one of quoted text. If
	      the option -q1bc is used,	the default value of  this  option  is
	      the background color or normal text.

       -q2fc  number of	color of text of level two of quoted text.

       -q2bc  number  of  color	 of background of level	two of quoted text. If
	      the option -q1bc is used,	the default value of  this  option  is
	      the background color or normal text.

       -q3fc  number of	color of text of level three of	quoted text.

       -sbfc  number of	color of text of signature block text.

       -sbbc  number of	color of background of signature block text.

Bugs
       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.
