@cindex mouse pointer

@vindex display-hourglass
@vindex hourglass-delay
On graphical displays, Emacs can optionally display the mouse pointer
in a special shape to say that Emacs is busy. To turn this feature on
or off, customize the group @code{cursor}. You can also control the
amount of time Emacs must remain busy before the busy indicator is
displayed, by setting the variable @code{hourglass-delay}.
On graphical displays, Emacs displays the mouse pointer as an
hourglass if Emacs is busy. To disable this feature, set the variable
@code{display-hourglass} to @code{nil}. The variable
@code{hourglass-delay} determines the number of seconds of ``busy
time'' before the hourglass is shown; the default is 1.
@vindex make-pointer-invisible
If the mouse pointer lies inside an Emacs frame, Emacs makes it
invisible each time you type a character to insert text, to prevent it
from obscuring the text. (To be precise, the hiding occurs when you
type a ``self-inserting'' character. @xref{Inserting Text}.) Moving
the mouse pointer makes it visible again. To disable this feature,
set the variable @code{make-pointer-invisible} to @code{nil}.
@vindex underline-minimum-offset
@vindex x-underline-at-descent-line
On graphical displays, the variable @code{underline-minimum-offset}
determines the minimum distance between the baseline and underline, in
pixels, for underlined text. By default, the value is 1; increasing
it may improve the legibility of underlined text for certain fonts.
(However, Emacs will never draw the underline below the current line
area.) The variable @code{x-underline-at-descent-line} determines how
to draw underlined text. The default is @code{nil}, which means to
draw it at the baseline level of the font; if you change it to
@code{nil}, Emacs draws the underline at the same height as the font's
descent line.
@vindex overline-margin
On graphical displays, the variable @code{overline-margin} specifies
the vertical position of an overline above the text, including the
height of the overline itself, in pixels. The default value is 2.
@vindex x-underline-at-descent-line
On graphical displays, Emacs normally draws an underline at the

@cindex avoiding mouse in the way of your typing
@cindex mouse avoidance
On graphical terminals, the mouse pointer may obscure the text in
the Emacs frame. Emacs provides two methods to avoid this problem.
@vindex make-pointer-invisible
Firstly, Emacs hides the mouse pointer each time you type a
self-inserting character, if the pointer lies inside an Emacs frame;
moving the mouse pointer makes it visible again. To disable this
feature, set the variable @code{make-pointer-invisible} to @code{nil}.
@vindex mouse-avoidance-mode
Mouse Avoidance mode keeps the mouse pointer away from point, to avoid
obscuring text you want to edit. Whenever it moves the mouse, it also
raises the frame. To use Mouse Avoidance mode, customize the variable
@code{mouse-avoidance-mode}. You can set this to various values to
move the mouse in several ways:
Secondly, you can use Mouse Avoidance mode, a minor mode, to keep
