+# Elements of tk::Priv that are used in this file:
+#
+# afterId -		If non-null, it means that auto-scanning is underway
+#			and it gives the "after" id for the next auto-scan
+#			command to be executed.
+# mouseMoved -		Non-zero means the mouse has moved a significant
+#			amount since the button went down (so, for example,
+#			start dragging out a selection).
+# pressX -		X-coordinate at which the mouse button was pressed.
+# selectMode -		The style of selection currently underway:
+#			char, word, or line.
+# x, y -		Last known mouse coordinates for scanning
+#			and auto-scanning.
+# data -		Used for Cut and Copy
+#-------------------------------------------------------------------------

+# The code below creates the default class bindings for entries.
