34-2 Editing Toolbar に選択ボタンを追加する「ol015-nippon_bmi_akiruno_pgis.html」 ファイルを続けて使います。
OpenLayers の Development Examples の「Editing Toolbar Example（http://openlayers.org/dev/examples/editingtoolbar.html）」と OpenLayers の
「Control」ページ
http://docs.openlayers.org/library/controls.html
の「Customizing an Existing Panel」を参考に Editing Toolbar に選択ボタンを追加してみます。

「displayClass」は、style を設定してアイコンを指定します。内容は "OpenLayers-2.13.1/theme/default/style.css" をコピーしました。
選択ボタンは次のようなものを作成して、"OpenLayers-2.13.1/theme/default/img/ に保存しました。
