-	 *   var cfg = editor.config; // this is the default configuration
-	 *   cfg.btnList["my-hilite"] =

-	 *	  "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

+    /* 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.
