	/* ADDING CUSTOM BUTTONS



	 * ---------------------



	 *



	 * It is recommended that you add the custom buttons in an external



	 * file and leave this one unchanged.  That's because when we



	 * (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.

 *



 * 1. config.registerButton("my-hilite", "Hilite text", "my-hilite.gif", false, function(editor) {...});
