help.ae

aee是一种易使用的文本编辑器。你可以不用说明书来使用它。它提供终端接口和本地的X-windows接口。它的特性包括即弹的菜单

causing the text between the slashes (/) to be inserted at the cursor position
when f8 is pressed.  The 'define' command may also be used in the file 
'init.ae' (see topic init.ae).


resequence

	The command 'resequence' renumbers the lines into proper sequence
from the top of the file to the bottom.  This command is useful if you have
inserted or deleted lines in the middle of the file, and wish to know how many
lines from the top you are.  


help

	The 'help' command is used to obtain this help facility.  To find the 
topic you want, look at the first selection presented, which may be obtained by
entering a TAB and pressing RETURN at the prompt at the bottom of your screen.
To exit, simply press RETURN in response to the prompt below and you will 
return to your edit session.  

	The entire name of the topic must be entered without any other 
characters before or after the topic name, otherwise this will confuse the help
facility.


eight
noeight

	The command 'eight' tells aee to send an eight bit character 
directly to the terminal rather than representing it in a different 
fashion.  Since some terminals do not have a character set which includes 
eight bit characters, aee allows the user to choose whether or not eight 
bit characters are represented by the eight bit value between angle 
brackets (251 is represented by <251>), or having the code sent directly 
to the terminal.  The command 'noeight' is used to tell aee to use the 
representation of the character, which is the default condition. 

	The command 'noeight' is used to tell aee to represent eight bit 
characters as the decimal value which represents the character between angle
brackets.  This is the default condition.

	These commands may be used in the file init.ae. See 'init.ae' for more
information.


tabs
untabs

	The command 'tabs' sets tab stops if used with arguments.  If used
without arguments, 'tabs' displays the stops set with previous 'tabs' commands.
Example:
	tabs 3 6 9 12

will set tab stops at columns 3, 6, 9, and 12.  After column 12, if the TAB key
is pressed, a tab will be inserted and the cursor will move to the next default
tab stop, in this case, column 16.  

	The command 'untabs' unsets tab stops that were set with previous 
'tabs' commands.  For example:

	untabs 6 12

will unset tab stops at columns 6 and 12 if tabs had been set there using a
previous 'tabs' command.

See also the 'spacing' and 'expand' commands.

	These commands may be used in the file init.ae. See 'init.ae' for more
information.

spacing

	The command 'spacing' will set the spacing for tabs to be the value 
specified for the number of spaces between tab stops.  This differs from the 
'tabs' command in that spacing is regular (while with 'tabs' spacing need not 
be regular stops).

Example:

	spacing 5

Will space tab stops every 5 spaces, like so:

     1    2    3    4    5

	This command may be used in the file init.ae. See 'init.ae' for more
information.

See also the 'tabs' and 'expand' commands for additional information


expand
noexpand

	The command 'expand' causes spaces to fill to the next tab stop when
the TAB key is pressed.  This is useful when you need to move to specific
columns (when used with the command 'tabs'), but do not want the tab character.

	The command 'noexpand' turns off tab expansion.

	These commands may be used in the file init.ae. See 'init.ae' for more
information.


justify
nojustify

	The command 'justify' tells aee to justify the right side of a 
paragraph during a 'format' operation.

	The command 'nojustfy' turns off right margin justification.

	These commands may be used in the file init.ae. See 'init.ae' for more
information.


autoformat
noautoformat

        The command 'autoformat' tells the editor to turn on auto paragraph 
formatting.  This means that when entering text, when a space is entered, the 
editor will make sure the text in the current paragraph fits into the set 
margins.  A paragraph is defined by a section of text bounded by the begin or 
end of files, and blank lines at the begin or end of the text block.

        The command 'noautoformat' turns off auto paragraph formatting.

	These commands may be used in the file init.ae. See 'init.ae' for more
information.

        In order for paragraph formatting to work, margins must be observed.  
When auto paragraph formatting is turned on, the editor is automatically 
notified to observe margins.  If however, the user later turns off margins, 
auto formatting will stop.


margin
nomargin

	The command 'margin' tells aee that you wish the length of a line 
limited to the right margin.  If in the course of typing you go beyond the 
right margin, aee will then start a new line, and move the characters from the 
first word that crosses the right margin to the new line.

	The command 'nomargin' tells the editor that the set margins are not 
to be observed.  

	These commands may be used in the file init.ae. See 'init.ae' for more
information.


rightmargin

	The command 'rightmargin' allows you to set or view a value for the 
right margin.  If you enter a value after 'rightmargin', that value will be 
used for the new right margin setting.  

	To view the current right margin setting, simply type 'rightmargin'.

	This command may be used in the file init.ae. See 'init.ae' for more
information.


leftmargin

	The command 'leftmargin' allows you to set or view a value for the 
left margin.  If you enter a value after 'leftmargin', that value will be 
used for the new left margin setting.  

	To view the current left margin setting, simply type 'leftmargin'.

	This command may be used in the file init.ae. See 'init.ae' for more
information.


status
nostatus

	The command 'status' turns on a status line at the bottom of the screen
which displays the name of the file, the line number, the column, and other
flags used by the editor.

	The command 'nostatus' turns off the status line.

	These commands may be used in the file init.ae. See 'init.ae' for more
information.


overstrike
nooverstrike

	The command 'overstrike' allows you to overwrite, or replace existing 
text, instead of inserting in the middle of a line.

	The command 'nooverstrike' turns off the 'overstrike' mode.

	These commands may be used in the file init.ae. See 'init.ae' for more
information.

indent
noindent

	The command 'indent' causes automatic indentation of a line created
by pressing the RETURN key to the same number of tabs and spaces as the 
previous line.

	The command 'noindent' turns off automatic indentation.

	These commands may be used in the file init.ae. See 'init.ae' for more
information.

print

	The command "print" will send the contents of the current buffer to a 
shell command (the default is the command "lp").  

	The shell command  can be redefined in the "init.ae" file by using 
the line option "printcommand", as follows:

	printcommand lp -dlaser

The above example will cause the "print" command to send the contents of the 
current buffer to the shell command "lp" with the option "-dlaser", which 
specifies the device "laser".  (See the UNIX reference page for "lp(1)" for 
more information.)


keys

	Aee uses a combination of function keys and control keys (a-z pressed 
along with the CONTROL or CTRL key) to perform operations in the editor.  These
keys may be redefined to the user's taste using the 'define' command.  The 
functions available are listed below.  The function name is followed in 
parenthesis by the symbol name used in defining the key. 
Enter the symbol or the name in response to the 'topic' prompt.

menu

	The 'menu' function causes a menu to pop up in the middle of the 
screen.  The menu contains entries for exiting the editor, getting help 
information, edit functions (cut/paste), file operations (read, write, save), 
screen redraw, file behavior settings (margins, etc.), search and replace, and 
miscellaneous operations (spell, paragraph formatting, shell escape).

	The menu function is initially assigned to the Escape key (or 
control-[ for keyboards without an escape key).  The menu is navigated by 
using the up and down arrow keys, the space bar and the backspace key.  Once 
the cursor is on the desired menu item, press the Return key to perform the 
task indicated.  

delete line
dl

	'Delete line' is initially assigned to control-L, as well as being
assigned to the key (if it is on your keyboard) DELETE LINE.  This function
may be assigned to a key using the symbol 'dl'.  'Delete line' deletes from 
the current cursor position to the end of the line, and appends the following
line to the end of the current line.  The line is placed in a buffer and may
be undeleted using the keyboard function 'undelete line', whose symbol is 
'udl'.  

See 'undelete line'.


clear to eol
cl

	'Clear to eol' is initially assigned to GOLD control-C, and may be 
assigned to a key using the symbol 'cl'.  'Clear to eol' deletes from 
the current cursor position to the end of the line, but does not append the 
following line to the end of the current line as does 'delete line'.  The 
line is placed in a buffer and may be undeleted using the keyboard function 
'undelete line', whose symbol is 'udl'.  

See 'undelete line'.


delete word
dw

	'Delete word' is initially assigned to the key control-W, and to f3.
This function may be assigned to a key using the symbol 'dw'.  Using this 
function you may delete from the current cursor position to the beginning of 
the next word.  For instance, if your cursor is placed on a character that is
not a 'space' or 'tab' character, then the characters to the next space or tab
will be deleted, and then the tabs and/or spaces to the next non-space 
character.  If your cursor is on a space or tab, the space characters up to 
the first non-space character are deleted.

	The word is placed in a buffer allowing you to undelete it by using
the command 'undelete character', symbol 'udw'.  

delete character
dc

	The default assignment for 'delete character' is control-K, and if your
terminal has it, the DELETE CHAR key.  'Delete character' may be assigned to a
key using the symbol 'dc'.  'Delete char' deletes the character the cursor is 
currently on.  Both 'delete character' and 'backspace' use the same buffer to 
store the last deleted character.  This buffer is accessed by using the 
function 'undelete character'.

undelete
und

	The function 'undelete' is not initially assigned.  'Undelete' does 
an undelete operation of the last delete operations, in reverse order of the 
delete operations.  The symbol for 'undelete' is 'und'.

undelete line
udl

	'Undelete line' is initially assigned to gold control-L, gold f2, and
to gold DELETE LINE, where DELETE LINE is a key on your keyboard.  The symbol
for 'undelete line' is 'udl'.  This function allows you to insert the most 
recently deleted line.  The line or partial line will be inserted in front of
the current cursor position, and will cause the text after the cursor to be at
the start of a new line.

undelete word
udw

	'Undelete word' is initially assigned to gold control-W, and gold f3.
The symbol for 'undelete word' is 'udw'.  This function allows you to insert
