        })
      },
 
      // source mode
      txtExec : function(caller) {
        var editor = this;
        $.sceditor.command.get('vid-facebook')._dropDown(editor, caller, function(id) {
          editor.insert('[youtube]' + id + '[/youtube]')
        })
      },
 
      tooltip: "Insert a YouTube video"
 
    });
 
    // add button to editor toolbar
    toolbar += ',vid-facebook';
  }
});
