the most recently deleted word at the cursor.

end of line
eol

	'End of line' is initially assigned to control-O and uses the symbol
'eol'.  'End of line' does exactly what you would expect it to do, which is
to move the cursor to the end of the current line.  If you are already at the
end of the line, 'end of line' will move the cursor to the end of the next 
line.

begin of line
bol

	'Begin of line' is initially assigned to control-D, and uses the symbol
'bol'.  'Begin of line' moves the cursor to the beginning of the current line.
If you are at the start of the current line, 'begin of line' will move you to 
the beginning of the previous line.

end of text
eot

	'End of text' is initially assigned to control-B, and uses the symbol 
'eot'.  'End of text' moves the cursor to the bottom of the current buffer.

begin of text
bot

	'Begin of text' is initially assigned to control-T, and uses the symbol
'bot'.  'Begin of text' moves the cursor to the top of the current buffer.

next page
np

	'Next page' is initially assigned to control-N, and if your terminal 
has it, the key NEXT PAGE.  'Next page' uses the symbol 'np'.  'Next page' 
moves the cursor forward several lines, depending on the size of your terminal 
screen, and the number of lines the current buffer occupies on the screen.

previous page
pp

	'Previous page' is initially assigned to control-P, and if your 
terminal has it, the key PREV PAGE.  'Previous page' uses the symbol 'pp'.
'Previous page' moves the cursor forward several lines, depending on the size 
of your terminal screen, and the number of lines the current buffer occupies on
the screen.

next buffer
nb

	'Next buffer' is initially assigned to gold control-N, and uses the 
symbol 'nb'.  'Next buffer' moves you to the next buffer in the order of buffer
creation.  If you have windows active, your cursor will be placed in the next
buffer, otherwise the screen is erased and the next buffer replaces the current
buffer on the screen.  The name of the buffer is also displayed on the command
line.

previous buffer
pb

	'Previous buffer' is initially assigned to gold control-P, and uses the
symbol 'pb'.  'Previous buffer' moves you to the previous buffer in the order
of buffer creation.  If you have windows active, your cursor will be placed in
the next buffer, otherwise the screen is erased and the next buffer replaces 
the current buffer on the screen.  The name of the buffer is also displayed on 
the command line.

gold

	'Gold' is initially assigned to control-G, and f1.  'Gold' allows the
user to have two functions assigned to keys, one is the function executed when
pressing the key, and the other is executed when the key is pressed immediately
after pressing the gold key.

	'Gold' also allows the user to repeat a single keystroke many times.  
Simply press the key assigned to GOLD, enter the number of repetitions you 
wish, then press the key you wish to be repeated (or GOLD and key).

insert line
il

	'Insert line' is initially assigned to the key INSERT LINE on your 
keyboard, and uses the symbol 'il'.  'Insert line' will terminate the line at
the current cursor position and put the rest of the line at the start of the
next line.  

search prompt
psrch

	'Search prompt' is initially assigned to the key gold control-F, and
gold f5.  'Search prompt' uses the symbol 'psrch'.  'Search prompt' causes a 
prompt to appear on the command line asking for the string to be found.  If 
you have executed the 'mark' function, all text from the current cursor 
position to the start of the string will be marked.  

	You may also use metacharacters in your search string, as well as 
have aee be case sensitive during search operations.  See topics 'case' 
and 'literal' for more information. 

	To search for a carriage return, a backspace, or control-v, press
control-v, and then the desired character.  The control-v character is required
since the backspace character is used for string editing, and carriage-return 
is used for string termination.


search
srch

	'Search' is initially assigned to control-F and f5, and uses the symbol
'srch'.  'Search' searches for the last string prompted for after executing
'search prompt'.  

replace prompt
prp

	'Replace prompt' is initially assigned to gold control-Z, and uses the 
symbol 'prp'.  'Replace prompt' asks the user for the string to be replaced,
and the string to replace it with.  This is accomplished by entering the 
initial string surrounded by a delimiter character which is not in the string 
itself, as follows:

	/old/new/

where "old" is the string to be found and replaced, and "new" is the string
to replace "old" with.

	You may also use metacharacters in your first string (the string to be
replaced), as well as have the search operation be case sensitive.  See the 
topics 'case' and 'literal'.

	It is possible to place the original string into the new string during
the replace operation, by inserting an ampersand (&) into the new string where
you wish to re-insert the old string.  This can only be done if in the 
'noliteral' mode.  To place an ampersand into the new string precede it with a
backslash (\).

see 'replace'

replace
rp

	'Replace' is initially assigned to control-Z, and uses the symbol 'rp'.
'Replace' uses the data obtained when the user executes the function 'replace
prompt' to search for a string and then replace it with the new string.  
'Replace' prompts the user each time it finds a match to the old string as to
whether or not to replace this occurrence.  The beginning of the old string
found is highlighted, and the prompt asks the user to respond with a carriage
return or 'r' to replace the string, 'a' to replace all occurrences, 's' to
skip this occurrence, or 'q' to quit replacing strings.

forward
fwd

	'Forward' is initially assigned to GOLD control-V, and uses the symbol
'fwd'.  'Forward' allows the user to specify that the next search or replace 
operation will search forward of the current cursor position.

reverse
rev

	'Reverse' is initially assigned to GOLD control-r, and uses the symbol
'rev'.  'Reverse' allows the user to specify that the next search or replace
operation will search above or before the current cursor position.

advance line
al

	'Advance line' is initially assigned to f8, and uses the symbol 'al'.
'Advance line' moves the cursor to the beginning of the next line.

advance word
aw

	'Advance word' is initially assigned to f4, and uses the symbol 'aw'.
'Advance word' moves the cursor forward to the next character after the 
following spaces and/or tabs.

previous word
pw

	'Previous word' is initially assigned to gold control-Y, and uses the 
symbol 'pw'.  'Previous word' moves the cursor to the first character of the 
word to the left of the current cursor position.

mark

	'Mark' is initially assigned to control-U and f6.  'Mark'  causes  the
text over which the cursor moves to be "marked" until you execute  either  the
'cut' or 'copy' function.  This causes the text to be  placed  into  a  buffer
so that you may place it elsewhere in your file using  the  'paste'  function.
You may delete the marked text (using the 'cut' function) or simply  copy  the
text (using the 'copy' function).  Once the text is in  the  buffer,  you  may
insert it anywhere in your buffer  as  many  times  as  you  like.   The  text
contained in the buffer before pressing 'mark' is lost. 

 
prefix

	'Prefix' is initially assigned to gold control-D, and uses the symbol 
'prefix'.  'Prefix' performs the same function as 'mark', except that the 
text marked is added to the current contents of the paste buffer (it is 
placed before the previous contents, hence 'prefix').

 
append

	'Append' is initially assigned to gold control-B, and uses the symbol 
'append'.  'Append' performs the same function as 'mark', except that the 
text marked is added to the current contents of the paste buffer (it is 
placed at the end of the previous contents, hence 'append').


paste
pst

	'Paste' is initially assigned to gold control-V and gold f7, and uses 
the symbol 'pst'.  'Paste' causes the text you placed into the paste buffer
using the 'mark' function to be inserted into the current buffer starting at 
the current cursor position.

cut

	'Cut' is initially assigned to control-X and f7.  'Cut' causes the 
marked text to be removed from the buffer.  You can insert this text in a 
buffer anywhere you wish by using the 'paste' function.

copy

	'Copy' is initially assigned to gold control-C and gold f6.  'Copy'
causes the marked text in the current buffer to be "unmarked", but still causes
it to be placed into the buffer for use with the 'paste' function.

unmark

	'Unmark' causes the marked test to be unmarked, and leaves the 
previous contents of the paste buffer intact.  The 'unmark' function is 
initially unassigned.  The symbol for 'unmark' is 'unmark'.

ascii character
ac

	'ASCII character' is initially assigned to control-A, and uses the 
symbol 'ac'.  'ASCII character' prompts the user form the decimal form of the
ASCII code for the desired character, and then inserts it at the current cursor
position.

match
mc

	'Match' is initially assigned to gold control-A, and uses the symbol
'mc'.  If the cursor is on a parenthesis (), a bracket [], a brace {}, or
angle bracket <>, 'match' will find the character which will be of the same 
level (skip nested characters), and place the cursor on it.


format

	'Format' is initially assigned to gold control-F, and uses the symbol 
'format'.  By pressing the function 'format', you will cause the paragraph in 
which the cursor currently resides to be left and right adjusted according 
the the current margin settings.  You must have 'nowrap' set, so that aee 
knows to observe the margins, otherwise no operations will occur.


command
cmd

	'Command' is initially assigned to control-E, and gold f8.
'Command' is assigned to so many keys because some people assign shell 
operations to various keys, and since this function is so vital, it is hoped
that no one will have assigned operations to all of the keys used for this 
function.  'Command' prompts the user for the name of the operation to be 
performed, and those operations are described under "commands" in the first 
topic selection.  'Command' uses the symbol 'cmd'.

up

	'Up' is initially assigned to the up-arrow key.  This function causes 
the cursor to move to the previous line in the same horizontal position it 
currently occupies.

down

	'Down' is initially assigned to the down-arrow key.  This function 
causes the cursor to move to the next line in the same horizontal position it
currently occupies.

left

	'Left' is initially assigned to the left-arrow key.  'Left' moves the
cursor to the left of the current cursor position, unless it is at the 
beginning of a line, in which case it moves to the last character of the 
previous line.

right

	'Right' is initially assigned to the right-arrow key.  'Right' moves 
the cursor to the right or the current cursor position, unless it is at the end
of the line, in which case it moves to the start of the next line.

redraw
rd

	'Redraw' is initially assigned to control-R, and uses the symbol 'rd'.
'Redraw' erases the screen and then redraws them, clearing the screen of any
garbage introduced by messages from outside the editor.

backspace
bck

	'Backspace' is initially assigned to the BACKSPACE key, and uses the 
symbol 'bck'.  'Backspace' deletes the character to the left of the cursor
and places it in a buffer.  The character may be "undeleted" using the function
'undelete character'.

carriage return
cr

	'Carriage return' is assigned to the RETURN key, and uses the symbol 
'cr'.  'Carriage return' terminates a line and moves the cursor to the start of
the next line.


init.ae

	The file 'init.ae' may be used to set parameters and define keys to 
perform certain functions within ae.  This file may reside in three 
locations: /usr/local/lib/init.ae, .init.ae in your home directory, and 
.init.ae in the current working directory.

        First, aee checks for a system level initialization file, located in 
/usr/local/lib.  Next the user's home directory is checked for a file named 
.init.ae, then the current directory.  The settings from each file are read, 
so that the directives from the most recently read file will take precedence 
over previously read files.  This allows, for example, the .init.ae file in 
the user's home directory to specify tab expansion, while the .init.ae file 
in the current working directory specifies no tab expansion.  This allows the 
user to establish global settings and to automatically override them for 
specific directories if desired. 

	The 'init.ae' file may be used to set aee to consider upper and lower
case (using the 'case' and 'nocase' commands), whether or not buffers will 
co-exist on the screen ('windows', 'nowindows'), and define function and 
control keys (the 'define' command).  See the above mentioned topics for 
details on syntax and usage.  An example follows:

	define ^l dl
	define gold ^l udl
	case
	nowindows

This file would disable windows, cause aee to be case sensitive, and define
control-L to execute the function 'delete line', and gold control-L to execute
the function 'undelete line'.
