.dc "make-backup-files" "(variable)"
If this variable is set, then whenever \s-2JOVE\s0 writes out a file, it will
move the previous version of the file (if there was one) to "#filename".
This is often convenient if you save a file by accident. The default
value of this variable is "off".
.IQ Note:
this is an optional part of
\s-2JOVE\s0, and your guru may not have it enabled, so it may not work.
.dc "make-buffer-unmodified" "ESC ~"
This makes \s-2JOVE\s0 think the selected buffer hasn't been changed even if
it has. Use this when you accidentally change the buffer but don't
want it considered changed. Watch the mode line to see the * disappear
when you use this command.
.dc "make-keymap" "Not Bound"
This creates an empty keymap with a name you supply. That name can be
used to reference the keymap in other commands, such as
bind-keymap-to-key.
.dc "make-macro-interactive" "Not Bound"
This command is meaningful only while you are defining a keyboard macro,
and when you are in the minibuffer. Ordinarily, when a command in a macro
definition requires a trailing text argument (file name, search string,
etc.), the argument you supply becomes part of the macro definition. If
you want to be able to supply a different argument each time the macro is
used, then while you are defining it, you should give the
make-macro-interactive command just before typing the argument which will
be used during the definition process. Note: you must bind this command
to a key in order to use it; you can't say "ESC X make-macro-interactive".
.dc "mark-threshold" "(variable)"
This variable contains the number of lines point may move by before
the mark is set. If, in a search or something, point moves by more
than this many lines, the mark is set so that you may return easily.
The default value of this variable is 22 (one screenful, on most
terminals).
.dc "marks-should-float" "(variable)"
When this variable is "off", the position of a mark is remembered as a line
number within the buffer and a character number within the line. If you add
or delete text before the mark, it will no longer point to the text you
marked originally because that text is no longer at the same line and
character number. When this variable is "on", the position of a mark is
adjusted to compensate for each insertion and deletion. This makes marks
much more sensible to use, at the cost of slowing down insertion and
deletion somewhat. The default value is "on".
.dc "match-regular-expressions" "(variable)"
When set, \s-2JOVE\s0 will match regular expressions in search patterns.
This makes special the characters ., *, [, ], ^, and $, and the two-character
sequences \e<, \e>, \e\|{, \e\|} and \e\||.
See the
.IQ ed(1)
manual page, the tutorial "Advanced Editing in
.UX
", and the section above "Searching with Regular Expressions"
for more information.
.dc "meta-key" "(variable)"
You should set this variable to "on" if your terminal has a real Meta key.
If your terminal has such a key, then a key sequence like ESC Y can be
entered by holding down Meta and typing Y. NOTE: In some systems, this
disables interrupting noninteractive shell commands.
.dc "mode-line" "(variable)"
The format of the mode line can be determined by setting this variable.
The items in the line are specified using a format similar to that used by printf(3),
with the special things being marked as "%x". Digits may be used between the
'%' and the 'x' to mean repeat that many times.
\&'x' may be:
.DS I
.ta .5i 1i 1.5i
C check for new mail, and displays "[New mail]" if there
is any (see also the mail-check-interval and disable-biff
variables)
F the current file name, with leading path stripped
M the current list of major and minor modes
b the current buffer name
c the fill character (-)
d the current directory
e extra space in modeline is distributed evenly
among the places %e is used (used for justifying,
separating, or centering parts of the modeline)
f the current file name
l the current load average (updated automatically)
mxy x, when the buffer is modified or y, when not
n the current buffer number
p interactive process status for process windows
s space, but only if previous character is not a space
t the current time (updated automatically)
w a '>' for windows which are scrolled left
[ ] the square brackets printed when in a recursive edit
( ) items enclosed in %( ... %) will only be printed on
the bottom mode line, rather than copied when the
window is split
.DE
In addition, any other character is simply copied into the mode line.
Characters may be escaped with a backslash. To get a feel for all
this, try typing "ESC X print mode-line" and compare the result with
your current mode line.
.dc "mode-line-color" "(variable)"
This specifies the color of the modeline (PC version only). Its default
value is 0, and in that case it is drawn in reverse video. If it has any
other value, this value is used as the attribute in the Bios calls.
.dc "mode-line-should-standout" "(variable)"
If set, the mode line will be printed in reverse video, if your
terminal supports it. The default for this variable is "off".
.dc "name-kbd-macro" "Not Bound"
This copies the keyboard macro and gives it a name freeing up the
keyboard macro so you can define some more. Keyboard macros with
their own names can be bound to keys just like built in commands
can. See the
.IQ define-macro,
.IQ source
and
.IQ write-macros-to-file
commands.
.dc "newline" "Return"
This divides the current line at point moving all the text to the
right of point down onto the newly created line. Point moves down to
the beginning of the new line.
.dc "newline-and-backup" "C-O"
This divides the current line at point moving all the text to the
right of point down onto the newly created line. The difference
between this and "newline" is that point does not move down to the
beginning of the new line.
.dc "newline-and-indent" "LineFeed"
This behaves the same was as Return does when in Auto Indent mode.
This makes Auto Indent mode obsolete but it remains in the name of
backward compatibility.
.dc "next-error" "C-X C-N"
This moves to the next error in the list of errors that were parsed
with
.IQ parse-errors.
In one window the list of errors is shown with the current one always at
the top. In another window is the file that contains the error. Point
is positioned in this window on the line where the error occurred.
.dc "next-line" "C-N"
This moves down to the next line.
.dc "next-page" "C-V"
This displays the next page of the buffer by taking the bottom line of
the window and redrawing the window with it at the top. If there isn't
another page in the buffer \s-2JOVE\s0 rings the bell. If a numeric argument
is supplied the screen is scrolled up that many lines; if the argument
is negative the screen is scrolled down.
.dc "next-window" "C-X N"
This moves into the next window. Windows live in a circular list so
when you're in the bottom window and you try to move to the next one
you are moved to the top window. It is an error to use this command
with only one window.
.dc "number-lines-in-window" "Not Bound"
This displays the line numbers for each line in the buffer being
displayed. The number isn't actually part of the text; it's just
printed before the actual buffer line is. To turn this off you run
the command again; it toggles.
.dc "over-write-mode" "Not Bound"
This turns Over Write mode on (or off if it's currently on) in the selected
buffer. When on, this mode changes the way the self-inserting characters
work. Instead of inserting themselves and pushing the rest of the line over
to the right, they replace or over-write the existing character. Also,
DEL replaces the character before point with a space instead of deleting
it. When Over Write mode is on "OvrWt" is displayed on the mode line.
.dc "page-next-window" "ESC C-V"
This displays the next page in the next window. This is exactly the
same as "C-X N C-V C-X P".
.dc "paren-flash" ") } ]"
This handles the C mode curly brace indentation, the Lisp mode paren
indentation, and the Show Match mode paren/curly brace/square bracket
flashing.
.dc "paren-flash-delay" "(variable)"
