edge. If you don't want this, customize the variable
@code{automatic-hscrolling} and set it to nil.
+If a window is scrolled horizontally by means of @code{scroll-left}, the
+chosen column serves as a lower bound for automatic horizontal
+scrolling. Automatic scrolling will continue to scroll the window to
+the left, if necessary, but won't scroll it more to the right than the
+column set by @code{scroll-left}.

(@samp{^}) followed by the non-control version of the character; thus,
control-A is displayed as @samp{^A}.
- Non-ASCII characters 0200 through 0377 are displayed with octal escape
-sequences; thus, character code 0243 (octal) is displayed as
-@samp{\243}. However, if you enable European display, most of these
-characters become non-ASCII printing characters, and are displayed using
-their graphics (assuming your terminal supports them).

+ Non-ASCII characters 0200 through 0237 (octal) are displayed with
+octal escape sequences; thus, character code 0230 (octal) is displayed
+as @samp{\230}. The display of character codes 0240 through 0377
+(octal) may be either as escape sequences or as graphics. They do not
+normally occur in multibyte buffers but if they do, they are displayed
+as Latin-1 graphics. In unibyte mode, if you enable European display
+they are displayed using their graphics (assuming your terminal supports
+them), otherwise as escape sequences. @xref{Single-Byte Character

@vindex mode-line-inverse-video
- The variable @code{mode-line-inverse-video} controls whether the mode
-line is displayed in inverse video (assuming the terminal supports it);
-@code{nil} means don't do so. @xref{Mode Line}. If you specify the
-foreground color for the @code{modeline} face, and
-@code{mode-line-inverse-video} is non-@code{nil}, then the default
-background color for that face is the usual foreground color.
-@xref{Faces}.
+ The variable @code{mode-line-inverse-video} is an obsolete way of
+controlling whether the mode line is displayed in inverse video; the
+preferred way of doing this is to change the @code{mode-line} face.
+@xref{Mode Line}. If you specify the foreground color for the
+@code{mode-line} face, and @code{mode-line-inverse-video} is

@vindex inverse-video
If the variable @code{inverse-video} is non-@code{nil}, Emacs attempts
elisp, The Emacs Lisp Reference Manual}.
@vindex baud-rate
- The variable @code{baud-rate} holds the output speed of the
-terminal, as far as Emacs knows. Setting this variable does not change
-the speed of actual data transmission, but the value is used for
-calculations such as padding. It also affects decisions about whether
-to scroll part of the screen or redraw it instead---even when using a
-window system. (We designed it this way, despite the fact that a window
-system has no true ``output speed,'' to give you a way to tune these
-decisions.)

+On window-systems, @code{baud-rate} is only used to determine how
+frequently to look for pending input during display updating. A higher
+value of @code{baud-rate} means that check for pending input will be
+done less frequently.
You can customize the way any particular character code is displayed
by means of a display table. @xref{Display Tables,, Display Tables,
