.dc "shell-command-no-buffer" "Not Bound"
This is just like
.IQ shell-command
except it just runs the command without saving the output to any buffer.
It will report the success of the command in the usual way.
.dc "shell-command-to-buffer" "Not Bound"
This is just like
.IQ shell-command
except it lets you specify the
buffer to use instead of \s-2JOVE\s0.
.dc "shell-command-with-typeout" "Not Bound"
This is just like
.IQ shell-command
except that instead of saving the output to a buffer, and displaying
it in a window, this just types out the output in the same way that
.IQ list-buffers
does.  Actually, how this behaves depends on the value of the variable
.IQ send-typeout-to-buffer.
If it is on then shell-command-with-typeout will behave just like
.IQ shell-command.
.dc "shell-flags" "(variable)"
This defines the flags that are passed to shell commands.  The default is
"-c".  See the
.IQ shell
variable to change the default shell.
.dc "shift-region-left" "Not Bound"
This shifts the region left by c-indentation-increment OR by the numeric
argument, if one is supplied.  If a negative argument is supplied the
region is shifted the other way.
.dc "shift-region-right" "Not Bound"
This shifts the region left by c-indentation-increment OR by the numeric
argument, if one is supplied.  If a negative argument is supplied the
region is shifted the other way.
.dc "show-match-mode" "Not Bound"
This turns on Show Match mode (or off if it's currently on) in the
selected buffer.  This changes "}", ")" and "]" so that when they are
typed the are inserted as usual, and then the cursor flashes back to the
matching "{", "(" or "[" (depending on what was typed) for about half a
second, and then goes back to just after the "}", ")" or "]" that invoked
the command.  This is useful for typing in complicated expressions in a
program.  You can change how long the cursor sits on the matching paren
by setting the "paren-flash-delay" variable in tenths of a second.  If
the matching "{", "(" or "[" isn't visible, the line containing the match
is displayed at the bottom of the screen.
.dc "shrink-window" "Not Bound"
This makes the current window one line shorter, if possible.  Windows
must be at least 2 lines high, one for the text and the other for the
mode line.
.dc "source" "Not Bound"
This reads a bunch of \s-2JOVE\s0 commands from a file.  The format of the
file is the same as that in your initialization file (your ".joverc")
in your main directory.  There should be one command per line and it
should be as though you typed "ESC X" while in \s-2JOVE\s0.  For example,
here's part of my initialization file:
.DS I
bind-to-key i-search-reverse ^R
bind-to-key i-search-forward ^S
bind-to-key pause-jove ^[S
.DE
What they do is make "C-R" call the
.IQ i-search-reverse
command and
"C-S" call
.IQ i-search-forward
and "ESC S" call
.IQ pause-jove.
.dc "spell-buffer" "Not Bound"
This runs the current buffer through the UNIX
.IQ spell
program and places
the output in buffer "Spell".  Then \s-2JOVE\s0 lets you edit the list of
words, expecting you to delete the ones that you don't care about, i.e., the
ones you know are spelled correctly.  Then the
.IQ parse-spelling-errors-in-buffer
command comes along and finds all the
misspelled words and sets things up so the error commands work.
.dc "split-current-window" "C-X 2"
This splits the current window into two equal parts (providing the
resulting windows would be big enough) and displays the selected buffer
in both windows.  Use "C-X 1" to go back to 1 window mode.  If a numeric
argument is supplied, the window is split "evenly" that many times (when
possible).
.dc "start-remembering" "C-X ("
This is just another name for the
.IQ begin-kbd-macro
name.  It is included for backward compatibility.
.dc "stop-process" "Not Bound"
This sends a stop signal (C-Z, for most people) to the current process.
It only works if you have the interactive process feature, and you are
in a buffer attached to a process.
.dc "stop-remembering" "C-X )"
This is just another name for the
.IQ end-kbd-macro
command.  It is included for backward compatibility.
.dc "string-length" "Not Bound"
This prints the number of characters in the string that point sits in.
Strings are surrounded by double quotes.  \s-2JOVE\s0 knows that "\e007" is
considered a single character, namely "C-G", and also knows about
other common ones, like "\er" (Return) and "\en" (LineFeed).  This is
mostly useful only for C programmers.
.dc "suspend-jove" "ESC S"
This is a synonym for
.IQ pause-jove.
.dc "sync-frequency" "(variable)"
The temporary files used by \s-2JOVE\s0 are forced out to disk every
.IQ sync-frequency
modifications.  The default is 50, which really makes
good sense.  Unless your system is very unstable, you probably
shouldn't fool with this.
.dc "tag-file" "(variable)"
This the name of the file in which \s-2JOVE\s0 should look up tag
definitions.  The default value is "./tags".
.dc "text-mode" "Not Bound"
This sets the major mode to Text.  Currently the other modes are
Fundamental, C and Lisp mode.
.dc "tmp-file-pathname" "(variable)"
This tells JOVE where to put the tmp files, which is where JOVE stores
buffers internally.  The default is usually in /tmp, but if you want to
store them somewhere else, you can set this variable.  If your system
crashes a lot it might be a good idea to set this variable to somewhere
other than /tmp because the system removes all the files in /tmp upon
reboot, and so you would not be able to recover editor buffers using the
"jove -r" command.

NOTE: In order for this to work correctly you must set this variable
BEFORE JOVE creates the tmp file.  You can set this in your .joverc (the
closer to tbe beginning the better), or as soon as you start up JOVE
before you visit any files.
.dc "transpose-characters" "C-T"
This switches the character before point with the one after point, and
then moves forward one.  This doesn't work at the beginning of the
line, and at the end of the line it switches the two characters before
point.  Since point is moved forward, so that the character that was
before point is still before point, you can use "C-T" to drag a
character down the length of a line.  This command pretty quickly
becomes very useful.
.dc "transpose-lines" "C-X C-T"
This switches the current line with the one above it, and then moves
down one so that the line that was above point is still above point.
This, like
.IQ transpose-characters,
can be used to drag a line down a page.
.dc "unbind-key" "Not Bound"
Use this to unbind
.IQ any
key sequence.  You can use this to unbind even a
prefix command, since this command does not use "key-map completion".  For
example, "ESC X unbind-key ESC [" unbinds the sequence "ESC [".  This is
useful for "turning off" something set in the system-wide ".joverc" file.
.dc "update-time-frequency" "(variable)"
How often the mode line is updated (and thus the time and load
average, if you display them).  The default is 30 seconds.
.dc "use-i/d-char" "(variable)"
If your terminal has insert/delete character capability you can tell \s-2JOVE\s0
not to use it by setting this to "off".  In my opinion it is only worth using
insert/delete character at low baud rates.  WARNING: if you set this to
"on" when your terminal doesn't have insert/delete character capability,
you will get weird (perhaps fatal) results.
.dc "version" "Not Bound"
Displays the version number of this \s-2JOVE\s0.
.dc "visible-bell" "(variable)"
Use the terminal's visible bell instead of beeping.  This is set
automatically if your terminal has the capability.
.dc "visible-spaces-in-window" "Not Bound"
This displays an underscore character instead of each space in the
window and displays a greater-than followed by spaces for each tab
in the window.  The actual text in the buffer is not changed; only
the screen display is affected.  To turn this off you run the command
again; it toggles.
.dc "visit-file" "C-X C-V"
This reads a specified file into the current buffer replacing the old
text.  If the buffer needs saving \s-2JOVE\s0 will offer to save it for you.
Sometimes you use this to start over, say if you make lots of changes
and then change your mind.  If that's the case you don't want \s-2JOVE\s0 to
save your buffer and you answer "NO" to the question.
.dc "window-find" "C-X 4"
This lets you select another buffer in another window three
different ways.  This waits for another character which can be one of
the following:
.DS I
.ta .5i 1i 1.5i
T	Finds a tag in the other window.
^T	Finds the tag at point in the other window
F	Finds a file in the other window.
B	Selects a buffer in the other window.
.DE
This is just a convenient short hand for "C-X 2" (or "C-X O" if there are
already two windows) followed by the appropriate sequence for invoking each
command.  With this, though, there isn't the extra overhead of having to
redisplay.  In addition, you don't have to decide whether to type "C-X 2" or
"C-X O" since "C-X 4" does the right thing.
.dc "word-abbrev-mode" "Not Bound"
This turns on Word Abbrev mode (or off if it's currently on) in the
selected buffer.  Word Abbrev mode lets you specify a word (an
abbreviation) and a phrase with which \s-2JOVE\s0 should substitute the
abbreviation.  You can use this to define words to expand into long
phrases, e.g., "jove" can expand into "Jonathan's Own Version of
Emacs"; another common use is defining words that you often misspell
in the same way, e.g., "thier" => "their" or "teh" => "the".  See
the information on the
.IQ auto-case-abbrev
variable.
.sp 1
There are two kinds of abbreviations: mode specific and global.  If you
define a Mode specific abbreviation in C mode, it will expand only in
buffers that are in C mode.  This is so you can have the same
abbreviation expand to different things depending on your context.
Global abbreviations expand regardless of the major mode of the buffer.
The way it works is this: \s-2JOVE\s0 looks first in the mode specific
table, and then in the global table.  Whichever it finds it in first is
the one that's used in the expansion.  If it doesn't find the word it is
left untouched. \s-2JOVE\s0 tries to expand words as they are typed, when
you type a punctuation character or Space or Return.  If you are in Auto
Fill mode the expansion will be filled as if you typed it yourself.
.dc "wrap-search" "(variable)"
If set, searches will "wrap around" the ends of the buffer instead
of stopping at the bottom or top.  The default is "off".
.dc "write-file" "C-X C-W"
This saves the current buffer to a specified file, and then makes that
file the default file name for this buffer.  If you specify a file
that already exists you are asked to confirm over-writing it.
.dc "write-files-on-make" "(variable)"
When set, all modified files will be written out before calling
make when the
.IQ compile-it
command is executed.  The default is "on".
.dc "write-macros-to-file" "Not Bound"
This writes the currently defined macros to a specified file in a format
appropriate for reading them back in with the
.IQ source
command.  The purpose of this command is to allow you to define macros
once and use them in other instances of JOVE.
.dc "write-modified-files" "C-X C-M"
This saves all the buffers that need saving.  If you supply a numeric
argument it asks for each buffer whether you really want to save it.
.dc "write-region" "Not Bound"
This writes the text in the region to a specified file.  If the file
already exists you are asked to confirm over-writing it.
.dc "write-word-abbrev-file" "Not Bound"
This writes the currently defined abbreviations to a specified file.
They can be read back in and automatically defined with
.IQ read-word-abbrev-file.
.dc "xterm-mouse" "Not Bound"
This function enables the use of the mouse with \S-2JOVE\fP in an
xterm window. The function is enabled when 'ansi-codes' is defined and
the function is bound to <escape><open-square-bracket>M.
Moving the mouse and pressing the left button will set the point
to the mouse position and push it.
Moving the mouse and pressing the right button will set the point
to the mouse position and yank the region from the last mark and the
current point.
Moving the mouse and pressing the middle button will set the point
to the mouse position and paste the contents of the mouse button in place.
Note that this in a \s-2JOVE\fP function and is independent of the normal
cut and paste operations available under xterm.
It is possible to bind these operations to SHIFT+the mouse button, so that
they will work in addition to \s-2JOVE\fP cut and paste.
.dc "yank" "C-Y"
This undoes the last kill command.  That is, it inserts the killed
text at point.  When you do multiple kill commands in a row, they are
merged so that yanking them back with "C\-Y" yanks back all of them.
.dc "yank-pop" "ESC Y"
This yanks back previous killed text.  \s-2JOVE\s0 has a kill ring on which
the last 10 kills are stored.
.IQ yank
yanks a copy of the text at the
front of the ring.  If you want one of the last ten kills you use "ESC
Y" which rotates the ring so another different entry is now at the
front.  You can use "ESC Y" only immediately following a "C-Y" or
another "ESC Y".  If you supply a negative numeric argument the ring
is rotated the other way.  If you use this command enough times in a
row you will eventually get back to where you started.  Experiment
with this.  It's extremely useful.
