@cindex pointer shape
@cindex mouse pointer shape
- These variables specify which shape to use for the mouse pointer in
-various situations, when using the X Window System:
+ You can specify the mouse pointer style for particular text or
+images using the @code{pointer} text property, and for images with the
+@code{:pointer} and @code{:map} image properties. The values you can
+use in these properties are @code{text} (or @code{nil}), @code{arrow},
+@code{hand}, @code{vdrag}, @code{hdrag}, @code{modeline}, and
+@code{hourglass}. @code{text} stands for the usual mouse pointer
+style used over text.
+
+ Over void parts of the window (parts that do not correspond to any
+of the buffer contents), the mouse pointer usually uses the
+@code{arrow} style, but you can specify a different style (one of
+those above) by setting @code{void-text-area-pointer}.
+
+@defvar void-text-area-pointer
+@tindex void-text-area-pointer
+This variable specifies the mouse pointer style for void text areas.
+These include the areas after the end of a line or below the last line
+in the buffer. The default is to use the @code{arrow} (non-text)
+pointer style.
+@end defvar
-@table @code
-@item x-pointer-shape
-@vindex x-pointer-shape
-This variable specifies the pointer shape to use ordinarily in the Emacs
-frame.
+ You can specify what the @code{text} pointer style really looks like
+by setting the variable @code{x-pointer-shape}.
-@item x-sensitive-text-pointer-shape
-@vindex x-sensitive-text-pointer-shape
+@defvar x-pointer-shape
+This variable specifies the pointer shape to use ordinarily in the

This variable specifies the pointer shape to use when the mouse

+
+@vindex x-dnd-test-function
+@vindex x-dnd-known-types
+ When a user drags something from another application over Emacs, that other
+application expects Emacs to tell it if Emacs can handle the data that is
+dragged. The variable @code{x-dnd-test-function} is used by Emacs to determine
+what to reply. The default value is @code{x-dnd-default-test-function}
+which accepts drops if the type of the data to be dropped is present in
+@code{x-dnd-known-types}. You can customize @code{x-dnd-test-function} and/or
+@code{x-dnd-known-types} if you want Emacs to accept or reject drops based
+on some other criteria.
+
+@vindex x-dnd-types-alist
+ If you want to change the way Emacs handles drop of different types
+or add a new type, customize @code{x-dnd-types-alist}. This requires
+detailed knowledge of what types other applications use for drag and
+drop.
+
+@vindex dnd-protocol-alist
+ When an URL is dropped on Emacs it may be a file, but it may also be
+another URL type (ftp, http, etc.). Emacs first checks
+@code{dnd-protocol-alist} to determine what to do with the URL. If
+there is no match there and if @code{browse-url-browser-function} is
+an alist, Emacs looks for a match there. If no match is found the
+text for the URL is inserted. If you want to alter Emacs behavior,
+you can customize these variables.
