+"""
+    Demonstration of setting an Element's Widget to use a different cursor than the
+    standard arrow.  In this case, the cursor is changed into a hand when hovering over the Text Element.
+
+    This implementation relies on accessing the underlying tkinter widget to change the cursor as there is currently no method provided for you to modify a widget's cursor.  Accessing an Element's tkinter widget is easy and straightforward, you simply write:
+            window[key].Widget
