+ * soft input mode. However, this mode gets rid of the soft keyboard on rotation,
+ * which is a probelm when the Search widget has focus. This special class
+ * changes Home's soft input method temporarily as long as the Search widget holds
+ * the focus. This way, the soft keyboard remains after rotation.
