2.1.3 The mode line
At the bottom of each editor window is a mode line that provides information concerning the buffer which that window is displaying. The contents of the mode line are as follows:
-
"LATIN-1" or "MACOS-ROMAN" or "UNICODE", or other encoding name, indicating the encoding of any file associated with the buffer.
-
"----" or "-**-" or "-%%-": the first indicates that the buffer is unchanged since it was last saved; the second that it has been changed; and the third that it is read only.
-
the
name of the buffer
(the name of a buffer originating from a file is usually the same as the name of that file).
-
the
package
of the current buffer written within braces.
-
a
major
mode
(such as Fundamental or Lisp). An buffer always operates in a single major mode.
-
a
minor mode
(such as Abbrev or Auto-Fill). If no minor mode is in operation then this element is omitted from the mode line. An editor can operate in any number of minor modes.
-
a
character position indicator
. This value indicates the position in the buffer of the first character displayed in the pane, expressed as a percentage of the total number of characters in the buffer. A value of 10 would indicate that the first character in the pane is 10% of the way through the buffer.
-
a
buffer position indicator.
This value indicates the percentage of the buffer that is currently displayed, and is separated from the character position indicator by a +. A value of 20 would indicate that a total of 20% of the buffer is currently shown.
-
the
pathname
with which the buffer is associated.
