 @cindex drag and drop
   Emacs supports drag and drop so that dropping of files and text is handeled.
-There is no drag support yet.  When text is dropped, Emacs will insert the
-text where it is dropped.  When a file is dragged from a file manager to
-Emacs, Emacs will open that file.
+Currently supported drag and drop protocols are XDND and the old KDE 1.x
+protocol.  There is no drag support yet. 
+When text is dropped, Emacs will insert the text where it is dropped.
+When a file is dragged from a file manager to Emacs, Emacs will open that file.
 As a special case, if a file is dropped on a dired buffer the file will
 be copied or moved (depends on exactly how it is dragged and the application
 is was dragged from) to the directory the dired buffer is displaying.
 
+@vindex x-dnd-open-file-other-window
   A file is normally opened in the window it is dropped on, but if you
 prefer the file to be opened in a new window, you can customize the variable
 @code{x-dnd-open-file-other-window}.
