This is John Chambers' tck/tk help window.   It  is  created
when you press the Help button (or F1 on keyboards that lack
a help button).  Point at any piece of the main  window  and
press  Help  (or  F1),  and if there is a help file for that
portion of the window, it will be displayed.

If no help file is found, you will  get  a  list  of  places
where  the  help routine looked.  This is for the benefit of
the people writing the help files.  You can pick one of  the
locations, create the file, and create the help files there.
If you try pointing at various parts  of  the  application's
window,  you  will  see  a  pattern:   The help file name is
derived by catenating either "help/" or  "/help/"  with  the
application's name, plus the name of the widget with all the
dots changed to "/".  The help window defaults to  60  chars
wide, so it's best if help files are limited to this width.

The little '*' button in the corner of the help window  will
close the help window.
