	 * (InteractiveTools.com) release a new official version, it's less
	 * likely that you will have problems upgrading HTMLArea.
	 *
	 * Example on how to add a custom button when you construct the HTMLArea:
	 *
	 *   var editor = new HTMLArea("your_text_area_id");
	 *   var cfg = editor.config; // this is the default configuration
	 *   cfg.btnList["my-hilite"] =
	 *	[ function(editor) { editor.surroundHTML('<span style="background:yellow">', '</span>'); }, // action
	 *	  "Highlight selection", // tooltip
	 *	  "my_hilite.gif", // image
	 *	  false // disabled in text mode
	 *	];
	 *   cfg.toolbar.push(["linebreak", "my-hilite"]); // add the new button to the toolbar
	 *
	 * An alternate (also more convenient and recommended) way to
	 * accomplish this is to use the registerButton function below.
