+
+    As with many text editors, the text editor widget can be configured
+    to insert or overwrite existing text with new text entered by the user.
+
+    If this property is \c true, existing text is overwritten, character-for-character
+    by new text; otherwise, text is inserted at the cursor position, displacing
+    existing text.
+
+    By default, this property is \c false (new text does not overwrite existing text).
