+ * AccessKey Hints
+ *
+ * Checks all HTML elements on this page that can have an accesskey attribute
+ * (<a>, <area>, <button>, <input>, <label>, <legend> and <textarea>)
+ * and creates or appends the title attribute to include platform-specific
+ * hint in the title, i.e. "Alt+S" (Win)
+ * or "Ctrl+S)" (Mac). If a title exists, a space plus the hint wrapped in
+ * parentheses is appended. The only exception is if the title already contains
+ * 'accesskey', 'Alt+' or 'Ctrl+' (case-insensitive) in which case this script
+ * will leave it alone.
+ *
+ *  Use the following markup to include the library:
+ *  <script type="text/javascript" src="access-key-hints.js"></script>
