+#
+# Removed the following standard Tk bindings:
+#
+# <Control-Key-space>, <Control-Shift-Key-space>,
+# <Key-Select>,  <Shift-Key-Select>:
+#	Ttk entry widget doesn't use selection anchor.
+# <Key-Insert>:
+#	Inserts PRIMARY selection (on non-Windows platforms).
+#	This is inconsistent with typical platform bindings.
+# <Double-Shift-ButtonPress-1>, <Triple-Shift-ButtonPress-1>:
+#	These don't do the right thing to start with.
+# <Meta-Key-b>, <Meta-Key-d>, <Meta-Key-f>,
+# <Meta-Key-BackSpace>, <Meta-Key-Delete>:
+#	Judgment call.  If <Meta> happens to be assigned to the Alt key,
+#	these could conflict with application accelerators.
+#	(Plus, who has a Meta key these days?)
+# <Control-Key-t>:
+#	Another judgment call.  If anyone misses this, let me know
+#	and I'll put it back.
