                    223: 	 * ---------------------
                    224: 	 *
                    225: 	 * It is recommended that you add the custom buttons in an external
                    226: 	 * file and leave this one unchanged.  That's because when we
                    227: 	 * (InteractiveTools.com) release a new official version, it's less
                    228: 	 * likely that you will have problems upgrading HTMLArea.
                    229: 	 *
                    230: 	 * Example on how to add a custom button when you construct the HTMLArea:
                    231: 	 *
                    232: 	 *   var editor = new HTMLArea("your_text_area_id");
                    233: 	 *   var cfg = editor.config; // this is the default configuration
                    234: 	 *   cfg.btnList["my-hilite"] =
                    235: 	 *	[ function(editor) { editor.surroundHTML('<span style="background:yellow">', '</span>'); }, // action
                    236: 	 *	  "Highlight selection", // tooltip
                    237: 	 *	  "my_hilite.gif", // image
                    238: 	 *	  false // disabled in text mode
                    239: 	 *	];
                    240: 	 *   cfg.toolbar.push(["linebreak", "my-hilite"]); // add the new button to the toolbar
                    241: 	 *
                    242: 	 * An alternate (also more convenient and recommended) way to
                    243: 	 * accomplish this is to use the registerButton function below.
