This section describes miscellaneous Windows-specific features.
The variable w32-use-visible-system-caret is a flag that
determines whether to make the system caret visible. The default when
no screen reader software is in use is
nil, which means Emacs
draws its own cursor to indicate the position of point. A
nil value means Emacs will indicate point location with the
system caret; this facilitates use of screen reader software, and is
the default when such software is detected when running Emacs.
When this variable is non-
nil, other variables affecting the
cursor display have no effect.
The variable w32-grab-focus-on-raise, if set to a
nil value causes a frame to grab focus when it is raised.
The default is t, which fits well with the Windows default
