* 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.
