.IQ yank
commands.
.dc "current-error" "Not Bound"
This moves to the current error in the list of parsed errors.  See the
.IQ next-error
and
.IQ previous-error
commands for more detailed
information.
.dc "date" "Not Bound"
This prints the date on the message line.
.dc "define-mode-word-abbrev" "Not Bound"
This defines a mode-specific abbreviation.
.dc "define-global-word-abbrev" "Not Bound"
This defines a global abbreviation.
.dc "delete-blank-lines" "C-X C-O"
This deletes all the blank lines around point.  This is useful when you
previously opened many lines with "C-O" and now wish to delete the
unused ones.
.dc "delete-buffer" "C-X K"
This deletes a buffer and frees up all the memory associated with it.
Be careful!  Once a buffer has been deleted it is gone forever.  \s-2JOVE\s0
will ask you to confirm if you try to delete a buffer that needs
saving.  This command is useful for when \s-2JOVE\s0 runs out of space to
store new buffers.
.dc "delete-macro" "Not Bound"
This deletes a macro from the list of named macros.  It is an error to
delete the keyboard-macro.  Once the macro is deleted it is gone forever.
If you are about to save macros to a file and decide you don't want to save
a particular one, delete it.
.dc "delete-next-character" "C-D"
This deletes the character that's just after point (that is, the
character under the cursor).  If point is at the end of a line, the
line separator is deleted and the next line is joined with the current
one.
.dc "delete-other-windows" "C-X 1"
This deletes all the other windows except the current one.  This can be
thought of as going back into One Window mode.
.dc "delete-previous-character" "Rubout"
This deletes the character that's just before point (that is, the
character before the cursor).  If point is at the beginning of the
line, the line separator is deleted and that line is joined with the
previous one.
.dc "delete-white-space" "ESC \\\\"
This deletes all the Tabs and Spaces around point.
.dc "delete-current-window" "C-X D"
This deletes the current window and moves point into one of the
remaining ones.  It is an error to try to delete the only remaining
window.
.dc "describe-bindings" "Not Bound"
This types out a list containing each bound key and the command that gets
invoked every time that key is typed.  To make a wall chart of \s-2JOVE\s0
commands, set
.IQ send-typeout-to-buffer
to "on" and \s-2JOVE\s0 will
store the key bindings in a buffer which you can save to a file and then
print.
.dc "describe-command" "Not Bound"
This prints some info on a specified command.
.dc "describe-key" "Not Bound"
This waits for you to type a key and then tells the name of the
command that gets invoked every time that key is hit.  Once you have
the name of the command you can use the
.IQ describe-command
command
to find out exactly what it does.
.dc "describe-variable" "Not Bound"
This prints some info on a specified variable.
.dc "digit" "ESC [0-9]"
This reads a numeric argument.  When you type "ESC" followed by a
number, "digit" keeps reading numbers until you type some other
command.  Then that command is executes with the numeric argument you
specified.
.dc "digit-1" "Not Bound"
This pretends you typed "ESC 1".  This is useful for terminals that
have keypads that send special sequences for numbers typed on the
keypad as opposed to numbers typed from the keyboard.  This can save
having type "ESC" when you want to specify an argument.
.dc "digit-2" "Not Bound"
This pretends you typed "ESC 2".  This is useful for terminals that
have keypads that send special sequences for numbers typed on the
keypad as opposed to numbers typed from the keyboard.  This can save
having type "ESC" when you want to specify an argument.
.dc "digit-3" "Not Bound"
This pretends you typed "ESC 3".  This is useful for terminals that
have keypads that send special sequences for numbers typed on the
keypad as opposed to numbers typed from the keyboard.  This can save
having type "ESC" when you want to specify an argument.
.dc "digit-4" "Not Bound"
This pretends you typed "ESC 4".  This is useful for terminals that
have keypads that send special sequences for numbers typed on the
keypad as opposed to numbers typed from the keyboard.  This can save
having type "ESC" when you want to specify an argument.
.dc "digit-5" "Not Bound"
This pretends you typed "ESC 5".  This is useful for terminals that
have keypads that send special sequences for numbers typed on the
keypad as opposed to numbers typed from the keyboard.  This can save
having type "ESC" when you want to specify an argument.
.dc "digit-6" "Not Bound"
This pretends you typed "ESC 6".  This is useful for terminals that
have keypads that send special sequences for numbers typed on the
keypad as opposed to numbers typed from the keyboard.  This can save
having type "ESC" when you want to specify an argument.
.dc "digit-7" "Not Bound"
This pretends you typed "ESC 7".  This is useful for terminals that
have keypads that send special sequences for numbers typed on the
keypad as opposed to numbers typed from the keyboard.  This can save
having type "ESC" when you want to specify an argument.
.dc "digit-8" "Not Bound"
This pretends you typed "ESC 8".  This is useful for terminals that
have keypads that send special sequences for numbers typed on the
keypad as opposed to numbers typed from the keyboard.  This can save
having type "ESC" when you want to specify an argument.
.dc "digit-9" "Not Bound"
This pretends you typed "ESC 9".  This is useful for terminals that
have keypads that send special sequences for numbers typed on the
keypad as opposed to numbers typed from the keyboard.  This can save
having type "ESC" when you want to specify an argument.
.dc "digit-0" "Not Bound"
This pretends you typed "ESC 0".  This is useful for terminals that
have keypads that send special sequences for numbers typed on the
keypad as opposed to numbers typed from the keyboard.  This can save
having type "ESC" when you want to specify an argument.
.dc "dirs" "Not Bound"
This prints out the directory stack.  See the "cd", "pushd", "popd"
commands for more info.
.dc "disable-biff" "(variable)"
When this is set, \s-2JOVE\s0 disables biff when you're editing and enables it
again when you get out of \s-2JOVE\s0, or when you pause to the parent shell
or push to a new shell. (This means arrival of new mail will not be
immediately apparent but will not cause indiscriminate writing on the
display). The default is "off".
.dc "dstop-process" "Not Bound"
Send the "dsusp" character to the current process.  This is the
character that suspends a process on the next read from the
terminal.  Most people have it set to C-Y.  This only works if
you have the interactive process feature, and if you are in a
buffer bound to a process.
.dc "edit-word-abbrevs" "Not Bound"
This creates a buffer with a list of each abbreviation and the phrase
it expands into, and enters a recursive edit to let you change the
abbreviations or add some more.  The format of this list is
"abbreviation:phrase" so if you add some more you should follow that
format.  It's probably simplest just to copy some already existing
abbreviations and edit them.  When you are done you type "C-X C-C" to
exit the recursive edit.
.dc "end-of-file" "ESC >"
This moves point forward to the end of the buffer.  This sometimes
prints the "Point Pushed" message.  If the end of the buffer isn't on
the screen \s-2JOVE\s0 will set the mark so you can go back to where you were
if you want.
.dc "end-of-line" "C-E"
This moves point to the end of the current line.  If the line is too
long to fit on the screen \s-2JOVE\s0 will scroll the line to the left to
make the end of the line visible.  The line will slide back to its
normal position when you move backward past the leftmost visible character
or when you move off the line altogether.
.dc "end-of-window" "ESC ."
This moves point to the last character in the window.
.dc "eof-process" "Not Bound"
Sends EOF to the current interactive process.  This only works on
versions of \s-2JOVE\s0 which run under 4.2-3 BSD VAX UNIX.  You can't send
EOF to processes on the 2.9 BSD PDP-11 UNIX.
.dc "erase-buffer" "Not Bound"
This erases the contents of the specified buffer.  This is like
.IQ delete-buffer
except it only erases the contents of the buffer, not
the buffer itself.  If you try to erase a buffer that needs saving you
will be asked to confirm it.
.dc "error-window-size" "(variable)"
This is the percentage of the screen to use for the error-window on the
screen.  When you execute
.IQ compile-it,
.IQ error-window-size
percent of the screen will go to the error window.  If the window already
exists and is a different size, it is made to be this size.  The default
value is 20%.
.dc "exchange-point-and-mark" "C-X C-X"
This moves point to mark and makes mark the old point.  This is for
quickly moving from one end of the region to another.
.dc "execute-named-command" "ESC X"
This is the way to execute a command that isn't bound to any key.
When you are prompted with ": " you can type the name of the
command.  You don't have to type the entire name.  Once the command
is unambiguous you can type Space and \s-2JOVE\s0 will fill in the rest for
you.
If you are not sure of the name of the command, type "?" and \s-2JOVE\s0
will print a list of all the commands that you could possibly match
given what you've already typed.  If you don't have any idea what the
command's name is but you know it has something to do with windows
(for example), you can do "ESC X apropos window" and \s-2JOVE\s0 will print a
list of all the commands that are related to windows.
If you find yourself constantly executing the same commands this way
you probably want to bind them to keys so that you can execute them
more quickly.  See the
.IQ bind-to-key
command.
.dc "execute-keyboard-macro" "C-X E"
This executes the keyboard macro.  If you supply a numeric argument the
macro is executed that many times.
.dc "execute-macro" "Not Bound"
This executes a specified macro.  If you supply a numeric argument the
macro is executed that many times.
.dc "exit-jove" "C-X C-C"
This exits \s-2JOVE\s0.  If any buffers need saving \s-2JOVE\s0 will print a warning
message and ask for confirmation.  If you leave without saving your
buffers all your work will be lost.  If you made a mistake and really
do want to exit then you can.  If you are in a recursive editing level
.IQ exit-jove
will return you from that.
.dc "file-creation-mode" "(variable)"
This variable has an octal value.
It contains the mode (see
.IQ chmod(1)
) with which files should be created.  This mode gets modified by your
current umask setting (see
.IQ umask(1)
).  The default value is usually
.IQ 0666
or
.IQ 0644.
.dc "files-should-end-with-newline" "(variable)"
This variable indicates that all files should always have a newline
at the end.  This is often necessary for line printers and the like.
When set, if \s-2JOVE\s0 is writing a file whose last character is not a
newline, it will add one automatically.
.dc "fill-comment" "Not Bound"
This command fills in your C comments to make them pretty and readable.
This filling is done according the variable
.IQ comment-format.
.DS L
/*
 * the default format makes comments like this.
 */
.DE
This can be changed by changing the format variable.  Other languages
may be supported by changing the format variable appropriately.  The
formatter looks backwards from dot for an open comment symbol.  If 
found, all indentation is done relative the position of the first character
of the open symbol.  If there is a matching close symbol, the entire 
comment is formatted.  If not, the region between dot and the open symbol
is reformatted.
.dc "fill-paragraph" "ESC J"
This rearranges words between lines so that all the lines in the current
paragraph extend as close to the right margin as possible, ensuring that
none of the lines will be greater than the right margin.  The default value
for
.IQ right-margin
is 78, but can be changed with the
.IQ set
and
.IQ right-margin-here
commands.  \s-2JOVE\s0 has a complicated algorithm
for determining the beginning and end of the paragraph.  In the normal case
\s-2JOVE\s0 will give all the lines the same indent as they currently have,
but if you wish to force a new indent you can supply a numeric argument to
.IQ fill-paragraph
(e.g., by typing C-U ESC J)
and \s-2JOVE\s0 will indent each line to the column
specified by the
.IQ left-margin
variable.  See also the
.IQ left-margin
variable and
.IQ left-margin-here
command.
.dc "fill-region" "Not Bound"
This is like
.IQ fill-paragraph,
except it operates on a region instead of
just a paragraph.
.dc "filter-region" "Not Bound"
This sends the text in the region to a UNIX command, and replaces the
region with the output from that command.  For example, if you are
lazy and don't like to take the time to write properly indented C
code, you can put the region around your C file and
.IQ filter-region
it
