NAME

     ee -- easy editor

SYNOPSIS

     ee [-eih] [+#] [file ...]
     ree [-eih] [+#] [file ...]

DESCRIPTION

     The ee utility is a simple screen oriented text editor.  It is always in
     text insertion mode unless there is a prompt at the bottom of the termi-
     nal, or a menu present (in a box in the middle of the terminal).  The ree
     utility is the same as ee, but restricted to editing the named file (no
     file operations, or shell escapes are allowed).

     For ee to work properly, the environment variable TERM must be set to
     indicate the type of terminal being used.	For example, for an HP 700/92
     terminal, the TERM variable should be set to "70092".  See your System
     Administrator if you need more information.

     The following options are available:

     -e      Turn off expansion of tab character to spaces.

     -i      Turn off display of information window at top of terminal.

     -h      Turn off highlighting of borders of windows and menus (improves
	     performance on some terminals).

     +#      Move the cursor to line '#' at startup.

   Control keys
     To do anything other than insert text, the user must use the control keys
     (the Control key, represented by a "^", pressed in conjunction with an
     alphabetic key, e.g., ^a) and function keys available on the keyboard
     (such as Next Page, Prev Page, arrow keys, etc.).

     Since not all terminals have function keys, ee has the basic cursor move-
     ment functions assigned to control keys as well as more intuitive keys on
     the keyboard when available.  For instance, to move the cursor up, the
     user can use the up arrow key, or ^u.

     ^a      Prompt for the decimal value of a character to insert.

     ^b      Move to the bottom of the text.

     ^c      Get the prompt for a command.

     ^d      Move the cursor down.

     ^e      Prompt for the string to search for.

     ^f      Undelete the last deleted character.

     ^g      Move to the beginning of the line.

     ^h      Backspace.

     ^m      Insert a newline.

     ^n      Move to the next page.

     ^o      Move to the end of the line.

     ^p      Move to the previous page.

     ^r      Move the cursor to the right.

     ^t      Move to the top of the text.

     ^u      Move the cursor up.

     ^v      Undelete the last deleted word.

     ^w      Delete the word beginning at the cursor position.

     ^x      Search.

     ^y      Delete from the cursor position to the end of line.

     ^z      Undelete the last deleted line.

     ^[ (ESC)
	     Pop up menu.

   EMACS keys mode
     Since many shells provide an Emacs mode (for cursor movement and other
     editing operations), some bindings that may be more useful for people
     familiar with those bindings have been provided.  These are accessible
     via the settings menu, or via the initialization file (see below).  The
     mappings are as follows:

     ^a      Move to the beginning of the line.

     ^b      Back 1 character.

     ^c      Command prompt.

     ^d      Delete character the cursor is sitting on.

     ^e      End of line.

     ^f      Forward 1 character.

     ^g      Go back 1 page.

     ^h      Backspace.

     ^i      Tab.

     ^j      Undelete last deleted character.

     ^k      Delete line.

     ^l      Undelete last deleted line.

     ^r      Restore last deleted word.

     ^t      Move to the top of the text.

     ^u      Move to the bottom of the text.

     ^v      Move to the next page.

     ^w      Delete the word beginning at the cursor position.

     ^y      Prompt for the string to search for.

     ^z      Next word.

     ^[ (ESC)
	     Pop up menu.

   Function Keys
     Next Page
	     Move to the next page.

     Prev Page
	     Move to the previous page.

     Delete Char
	     Delete the character the cursor is on.

     Delete Line
	     Delete from the cursor to the end of line.

     Insert line
	     Insert a newline at the cursor position.

     Arrow keys
	     Move the cursor in the direction indicated.

   Commands
     Some operations require more information than a single keystroke can pro-
     vide.  For the most basic operations, there is a menu that can be
     obtained by pressing the ESC key.	The same operations, and more can be
     performed by obtaining the command prompt (^c) and typing in one of the
     commands below.

     !cmd    Execute cmd in a shell.

     0-9     Move to the line indicated.

     case    Make searches case sensitive.

     character
	     Display the ASCII value of the character at the cursor.

     exit    Save the edited text, and leave the editor.

     expand  Expand tabs to spaces.

     file    Print the name of the file.


     quit    Leave the editor without saving changes.

     read file
	     Read the named file.

     write file
	     Write the text to the named file.

   Menu Operations
     Pop-up menus can be obtained by pressing the escape key (or ^[ if no
     escape key is present).  When in the menu, the escape key can be used to
     leave the menu without performing any operations.	Use the up and down
     arrow keys, or ^u for moving up and ^d for moving down to move to the
     desired items in the menu, then press return to perform the indicated
     task.

     To the left of each menu item is a letter, which if the corresponding
     letter is pressed on the keyboard selects that menu entry.

     The main menu in ee is as follows:

     leave editor
	     If changes have been made, the user will get a menu prompting
	     whether or not the changes should be saved.

     help    Display a help screen, with all of the keyboard operations and
	     commands.

     file operations
	     Pop up a menu for selecting whether to read a file, write to a
	     file, or save the current contents of the editor, as well as send
	     the contents of the editor to a print command (see the section
	     Initializing ee from a file).

     redraw screen
	     Provide a means to repaint the screen if the screen has been cor-
	     rupted.

     settings
	     Show the current values of the operating modes, and right margin.
	     By pressing return when the cursor is on a particular item, the
	     value can be changed.  To leave this menu, press the escape key.
	     (See Modes below.)

     search  Pop up a menu in which the user may choose to enter a string to
	     search for, or search for a string already entered.

     miscellaneous
	     Pop up a menu that allows the user to format the current para-
	     graph, execute a shell command, or check the spelling of the text
	     in the editor.

   Paragraph Formatting
     Paragraphs are defined for ee by a block of text bounded by:

     o	     Begin or end of file.

     There are three states for text operation in ee: free-form, margins, and
     automatic formatting.

     "Free-form" is best used for things like programming.  There are no
     restrictions on the length of lines, and no formatting takes place.

     "Margins" allows the user to type in text without having to worry about
     going beyond the right margin (the right margin may be set in the
     settings menu, the default is for the margin to be the right edge of the
     terminal).  This is the mode that allows the format paragraph menu item
     to work.

     "Automatic formatting" provides word-processor-like behavior.  The user
     may type in text, while ee will make sure the entire paragraph fits
     within the width of the terminal every time the user inserts a space
     after typing or deleting text.  Margin observation must also be enabled
     in order for automatic formatting to occur.

   Modes
     Although ee is a 'modeless' editor (it is in text insertion mode all the
     time), there are modes in some of the things it does.  These include:

     tab expansion
	     Tabs may be inserted as a single tab character, or replaced with
	     spaces.

     case sensitivity
	     The search operation can be sensitive to whether characters are
	     upper- or lower-case, or ignore case completely.

     margins observed
	     Lines can either be truncated at the right margin, or extend on
	     forever.

     auto paragraph formatting
	     While typing in text, the editor can try to keep it looking rea-
	     sonably well within the width of the screen.

     eightbit characters
	     Toggle whether eight bit characters are displayed as their value
	     in angle brackets (e.g. "<220>") or as a character.

     info window
	     A window showing the keyboard operations that can be performed
	     can be displayed or not.

     emacs keys
	     Control keys may be given bindings similar to emacs, or not.

     16 bit characters
	     Toggles whether sixteen bit characters are handled as one 16-bit
	     quantities or two 8-bit quantities.  This works primarily with
	     the Chinese Big 5 code set.

     You may set these modes via the initialization file (see below), or with
     a menu (see above).

   Spell Checking

   Printing the contents of the editor
     The user may select a menu item which prints the contents of the editor.
     The ee utility pipes the text in the editor to the command specified by
     the initialization command printcommand (see the section Initializing ee
     from a file below).  The default is to send the contents to lp(1).

     Whatever the user assigns to printcommand must take input from standard
     input.  See your system administrator for more details.

   Shell operations
     Shell commands can be executed from within ee by selecting the shell
     command item in the miscellaneous menu, or by placing an exclamation mark
     ("!") before the command to execute at the command: prompt.  Addition-
     ally, the user may direct the contents of the edit buffer out to a shell
     operation (via a pipe) by using the left angle bracket (">"), followed by
     a "!" and the shell command to execute.  The output of a shell operation
     can also be directed into the edit buffer by using a right angle bracket
     ("<") before the exclamation mark.  These can even be used together to
     send output to a shell operation and read back the results into the edi-
     tor.  So, if the editor contained a list of words to be sorted, they
     could be sorted by typing the following at the command prompt:
	   ><!sort
     This would send the contents of the editor to be piped into the sort(1)
     utility and the result would be placed into the edit buffer at the cur-
     rent cursor location.  The old information would have to be deleted by
     the user.

   Initializing ee from a file
     Since different users have different preferences, ee allows some slight
     configurability.  There are three possible locations for an initializa-
     tion file for ee: the file /usr/share/misc/init.ee, the file .init.ee in
     the user's home directory, or the file .init.ee in the current directory
     (if different from the home directory).  This allows system administra-
     tors to set some preferences for the users on a system-wide basis (for
     example, the print command), and the user to customize settings for par-
     ticular directories (like one for correspondence, and a different direc-
     tory for programming).

     The file /usr/share/misc/init.ee is read first, then $HOME/.init.ee, then
     .init.ee, with the settings specified by the most recent file read taking
     precedence.

     The following items may be entered in the initialization file:

     case    Set searches to be case sensitive.

     nocase  Set searches to be insensitive to case (default).

     expand  Cause ee to expand tabs to spaces (default).

     noexpand
	     Cause ee to insert tabs as a single character.

     info    A small information window is displayed at the top of the termi-
	     nal (default).

     noinfo  Turn off the display of the information window.

     autoformat
	     Cause ee to automatically try to format the current paragraph
	     while text insertion is occurring.

     noautoformat
	     Turn off automatic paragraph formatting (default).

     printcommand
	     Allow the setting of the print command (default: "lp").

     rightmargin
	     The user can select a value for the right margin (the first col-
	     umn on the screen is zero).

     highlight
	     Turn on highlighting of border of information window and menus
	     (default).

     nohighlight
	     Turn off highlighting of border of information window and menus.

     eightbit
	     Turn on display of eight bit characters.

     noeightbit
	     Turn off display of eight bit characters (they are displayed as
	     their decimal value inside angle brackets, e.g., "<220>").

     16bit   Turns on handling of 16-bit characters.

     no16bit
	     Turns off handling of 16-bit characters.

     emacs   Turns on emacs key bindings.

     noemacs
	     Turns off emacs key bindings.

   Save Editor Configuration
     When using this entry from the settings menu, the user may choose to save
     the current configuration of the editor (see Initializing ee from a file
     above) to a file named .init.ee in the current directory or the user's
     home directory.  If a file named .init.ee already exists, it will be
     renamed .init.ee.old.
