            theme_advanced_buttons2 :  "mybutton,|,link,unlink,|,hr,removeformat,pastetext,pasteword,cleanup,|,undo,redo,|,code",
            theme_advanced_toolbar_location : "top",
            theme_advanced_toolbar_align : "left",
            theme_advanced_statusbar_location : "none",
            theme_advanced_resizing : true,
            convert_urls : false,
            fullpage_default_doctype: "",

        content_css : "css/content.css",
        cleanup : false,

        template_external_list_url : "lists/template_list.js",
        external_link_list_url : "lists/link_list.js",
        external_image_list_url : "lists/image_list.js",
        media_external_list_url : "lists/media_list.js",

    });
