LISP hackers, the prompt can be
.DS
"% \e|-> \e|<[0-9]>: ".
.DE
.dc "process-send-data-no-return" "Not Bound"
This is like
.IQ process-newline
except it sends everything to the process without the newline.  Normally,
when you type return in a process buffer it sends everything you typed
including the Return.  This command just provides a way to send data to
the process without having to send a newline as well.
.dc "push-shell" "Not Bound"
This spawns a child shell and relinquishes control to it.  This works
on any version of UNIX, but this isn't as good as
.IQ pause-jove
because
it takes time to start up the new shell and you get a brand new
environment every time.  To return to \s-2JOVE\s0 you type "C-D".
.dc "pushd" "Not Bound"
This pushes a directory onto the directory stack and cd's into it.  It
asks for the directory name but if you don't specify one it switches
the top two entries no the stack.  It purposely behaves the same as
C-shell's
.IQ pushd.
.dc "pwd" "Not Bound"
This prints the working directory.
.dc "query-replace-string" "ESC Q"
This replaces the occurrences of a specified string with a specified
replacement string.  When an occurrence is found point is moved to it
and then \s-2JOVE\s0 asks what to do.  The options are:
.DS I
.ta \w'DEL111'u
Space	to replace this occurrence and go on to the next one.
Period	to replace this occurrence and then stop.
DEL	to skip this occurrence and go on to the next one.
C-R	to enter a recursive edit.  This lets you temporarily
	suspend the replace, do some editing, and then return
	to continue where you left off.  To continue with the
	Query Replace type "C-X C-C" as if you were trying to
	exit \s-2JOVE\s0.  Normally you would but when you are in a
	recursive edit all it does is exit that recursive
	editing level.
C-W	to delete the matched string and then enter a recursive
	edit.
U	to undo all changes to the last modified line.
P or !	to go ahead and replace the remaining occurrences without
	asking.
Return	to stop the Query Replace.
.DE
The search for occurrences starts at point and goes to the end of the
buffer, so to replace in the entire buffer you must first go to the
beginning.
.dc "quit-process" "Not Bound"
This is the same as typing "C-\e" (the Quit character) to a normal UNIX
process, except it sends it to the current process in \s-2JOVE\s0.  This is
only for versions of \s-2JOVE\s0 that have the interactive processes feature.
This only works when you are inside a buffer that's attached to a
process.
.dc "quoted-insert" "C-Q"
This lets you insert characters that normally would be executed as
other \s-2JOVE\s0 commands.  For example, to insert "C-F" you type "C-Q C-F".
.dc "read-only-mode" "Not Bound"
Read-only-mode is a minor mode.  It puts a buffer in read-only mode, so
that any attempts to modify the buffer fail.  When a file is found, and
it's not got write permission, JOVE automatically puts the buffer in
read-only mode.  This is very helpful when you are in environments which
use source control programs like RCS and SCCS.  It prevents accidents
like making a bunch of changes and only THEN discovering that you haven't
checked the file out for making changes.  This, like other minor modes,
toggles.
.dc "read-word-abbrev-file" "Not Bound"
This reads a specified file that contains a bunch of abbreviation
definitions, and makes those abbreviations available.  If the selected
buffer is not already in Word Abbrev mode this command puts it in
that mode.
.dc "recursive-edit" "Not Bound"
This enters a recursive editing level.  This isn't really very
useful.  I don't know why it's available for public use.  I think I'll
delete it some day.
.dc "redraw-display" "C-L"
This centers the line containing point in the window.  If that line is
already in the middle the window is first cleared and then redrawn.
If a numeric argument is supplied, the line is positioned at that
offset from the top of the window.  For example, "ESC 0 C-L" positions
the line containing point at the top of the window.
.dc "rename-buffer" "Not Bound"
This lets you rename the current buffer.
.dc "replace-in-region" "Not Bound"
This is the same as
.IQ replace-string
except that it is restricted
to occurrences between Point and Mark.
.dc "replace-string" "ESC R"
This replaces all occurrences of a specified string with a specified
replacement string.  This is just like
.IQ query-replace-string
except
it replaces without asking.
.dc "right-margin" "(variable)"
Where the right margin is for
.IQ "Auto Fill"
mode and the
.IQ justify-paragraph
and
.IQ justify-region
commands.  The default is 78.
.dc "right-margin-here" "Not Bound"
This sets the
.IQ right-margin
variable to the current position of
point.  This is an easy way to say, "Make the right margin begin here,"
without having to count the number of spaces over it actually is.
.dc "save-file" "C-X C-S"
This saves the current buffer to the associated file.  This makes your
changes permanent so you should be sure you really want to.  If the
buffer has not been modified
.IQ save-file
refuses to do the save.  If
you really do want to write the file you can use "C-X C-W" which
executes
.IQ write-file.
.dc "scroll-all-lines" "(variable)"
When this is turned on, the entire window will be scrolled left or right
when the current line scrolls.  The default value is OFF, which will
cause \s-2JOVE\s0 to behave in the familiar way, namely to scroll only
the current line.
.dc "scroll-down" "ESC Z"
This scrolls the screen one line down.  If the line containing point
moves past the bottom of the window point is moved up to the center of
the window.  If a numeric argument is supplied that many lines are
scrolled; if the argument is negative the screen is scrolled up
instead.
.dc "scroll-left" "Not Bound"
This scrolls the text in the current window 10 character positions to the
left.  If a numeric argument is specified then the text is scrolled that
number of character positions.  If the variable
.IQ scroll-all-lines
is ON then
.IQ scroll-left
may actually do nothing if the scrolling would cause Point not to be
visible.
.dc "scroll-next-page" "Not Bound"
This continuously scrolls up screen-full lines (PC version only).
.dc "scroll-previous-page" "Not Bound"
This continuously scrolls down screen-full lines (PC version only).
.dc "scroll-right" "Not Bound"
This scrolls the text in the current window 10 character positions to the
right.  If a numeric argument is specified then the text is scrolled that
number of character positions.  If the variable
.IQ scroll-all-lines
is ON then
.IQ scroll-right
may actually do nothing if the scrolling would cause Point not to be
visible.
.dc "scroll-step" "(variable)"
How many lines should be scrolled if the
.IQ previous-line
or
.IQ next-line
commands move you off the top or bottom of the screen.  You may wish to
decrease this variable if you are on a slow terminal.  The default value
is 0, which means to center the current line in the window.  If the value
is negative, the behavior is slightly different.  If you move off the top
of the window, and
.IQ scroll-step
is, say, -5 then the new line will be displayed 5 lines from the bottom
of the window.  If you move off the bottom of the window, the new line
will be positioned 5 lines from the top of the window.
.dc "scroll-up" "C-Z"
This scrolls the screen one line up.  If the line containing point
moves past the top of the window point is moved down to the center of
the window.  If a numeric argument is supplied that many lines are
scrolled; if the argument is negative the screen is scrolled down
instead.
.dc "search-exit-char" "(variable)"
Set this to the character you want to use to exit incremental search.
The default is Newline, which makes i-search compatible with normal
string search.
.dc "search-forward" "C-S"
This searches forward for a specified search string and positions
point at the end of the string if it's found.  If the string is not
found point remains unchanged.  This searches from point to the end of
the buffer, so any matches before point will be missed.
.dc "search-forward-nd" "Not Bound"
This is just like
.IQ search-forward
except that it doesn't assume a default search string, and it doesn't set
the default search string.  This is useful for defining macros, when you
want to search for something, but you don't want it to affect the current
default search string.
.dc "search-reverse" "C-R"
This searches backward for a specified search string and positions
point at the beginning if the string if it's found.  If the string is
not found point remains unchanged.  This searches from point to the
beginning of the buffer, so any matches after point will be missed.
.dc "search-reverse-nd" "Not Bound"
This is just like
.IQ search-reverse
except that it doesn't assume a default search string, and it doesn't set
the default search string.  This is useful for defining macros, when you
want to search for something, but you don't want it to affect the current
default search string.
.dc "select-buffer" "C-X B"
This selects a new or already existing buffer making it the current
one.  You can type either the buffer name or number.  If you type in
the name you need only type the name until it is unambiguous, at which
point typing Escape or Space will complete it for you.  If you want to
create a new buffer you can type Return instead of Space, and a new
empty buffer will be created.
.dc "select-buffer-1" "<Alt>-0"
This selects buffer number 0, if it exists (PC version only).
.dc "select-buffer-1" "<Alt>-1"
This selects buffer number 1, if it exists (PC version only).
.dc "select-buffer-2" "<Alt>-2"
This selects buffer number 2, if it exists (PC version only).
.dc "select-buffer-3" "<Alt>-3"
This selects buffer number 3, if it exists (PC version only).
.dc "select-buffer-4" "<Alt>-4"
This selects buffer number 4, if it exists (PC version only).
.dc "select-buffer-5" "<Alt>-5"
This selects buffer number 5, if it exists (PC version only).
.dc "select-buffer-6" "<Alt>-6"
This selects buffer number 6, if it exists (PC version only).
.dc "select-buffer-7" "<Alt>-7"
This selects buffer number 7, if it exists (PC version only).
.dc "select-buffer-8" "<Alt>-8"
This selects buffer number 8, if it exists (PC version only).
.dc "select-buffer-9" "<Alt>-9"
This selects buffer number 9, if it exists (PC version only).
.dc "self-insert" "Most Printing Characters"
This inserts the character that invoked it into the buffer at point.
Initially all but a few of the printing characters are bound to
.IQ self-insert.
.dc "send-typeout-to-buffer" "(variable)"
When this is set \s-2JOVE\s0 will send output that normally overwrites the
screen (temporarily) to a buffer instead.  This affects commands like
.IQ list-buffers,
.IQ list-processes,
and commands that use completion.  The default value is "off".
.dc "set" "Not Bound"
This gives a specified variable a new value.  Occasionally you'll see
lines like "set this variable to that value to do this".  Well, you
use the
.IQ set
command to do that.
.dc "set-mark" "C-@"
This sets the mark at the current position in the buffer.  It prints
the message "Point pushed" on the message line.  It says that instead
of "Mark set" because when you set the mark the previous mark is still
remembered on a ring of 16 marks.  So "Point pushed" means point is
pushed onto the ring of marks and becomes the value of "the mark".
To go through the ring of marks you type "C-U C-@", or execute the
.IQ pop-mark
command.  If you type this enough times you will get back
to where you started.
.dc "shell" "(variable)"
The shell to be used with all the shell commands command.  If your SHELL
environment variable is set, it is used as the value of
.IQ shell;
otherwise "/bin/csh" is the default.
.dc "shell" "Not Bound"
This starts up an interactive shell in a window.  \s-2JOVE\s0 uses
"*shell*" as the name of the buffer in which the interacting takes
place.  See the manual for information on how to use interactive
processes.
.dc "shell-command" "C-X !"
This runs a UNIX command and places the output from that command in a
buffer.  \s-2JOVE\s0 creates a buffer that matches the name of the command
you specify and then attaches that buffer to a window.  So, when you
have only one window running this command will cause \s-2JOVE\s0 to split the
window and attach the new buffer to that window.  Otherwise, \s-2JOVE\s0
finds the most convenient of the available windows and uses that one
instead.  If the buffer already exists it is first emptied, except that if
it's holding a file, not some output from a previous command, \s-2JOVE\s0
prints an error message and refuses to execute the command.  If you
really want to execute the command you should delete that buffer
(saving it first, if you like) or use
.IQ shell-command-to-buffer,
