@defvar mode-line-modified
This variable holds the value of the mode-line construct that displays
whether the current buffer is modified.
The default value of @code{mode-line-modified} is @code{("%1*%1+")}.
This means that the mode line displays @samp{**} if the buffer is
modified, @samp{--} if the buffer is not modified, @samp{%%} if the
buffer is read only, and @samp{%*} if the buffer is read only and
modified.
whether the current buffer is modified. Its default value displays
@samp{**} if the buffer is modified, @samp{--} if the buffer is not
modified, @samp{%%} if the buffer is read only, and @samp{%*} if the
buffer is read only and modified.
Changing this variable does not force an update of the mode line.

@defvar mode-line-frame-identification
This variable identifies the current frame. The default value is
@code{" "} if you are using a window system which can show multiple
frames, or @code{"-%F "} on an ordinary terminal which shows only one
frame at a time.

@defvar mode-line-buffer-identification
This variable identifies the buffer being displayed in the window. Its
default value is @code{("%12b")}, which displays the buffer name, padded
with spaces to at least 12 columns.

@defvar mode-line-position
This variable indicates the position in the buffer. Here is a
simplified version of its default value. The actual default value
also specifies addition of the @code{help-echo} text property.
@example
@group
((-3 "%p")
(size-indication-mode (8 " of %I"))
@end group
@group
(line-number-mode
((column-number-mode
(10 " (%l,%c)")
(6 " L%l")))
((column-number-mode
(5 " C%c")))))
@end group
@end example
This means that @code{mode-line-position} displays at least the buffer
percentage and possibly the buffer size, the line number and the column
number.
This variable indicates the position in the buffer. Its default value
displays the buffer percentage and, optionally, the buffer size, the

@defvar mode-line-modes
This variable displays the buffer's major and minor modes. Here is a
simplified version of its default value. The real default value also
specifies addition of text properties.
@example
@group
("%[(" mode-name

@end group
@end example
So @code{mode-line-modes} normally also displays the recursive editing
level, information on the process status and whether narrowing is in
effect.
