+ * Main API function for adding a button to Quicktags
+ *
+ * Adds qt.Button or qt.TagButton depending on the args. The first three args are always required.
+ * To be able to add button(s) to Quicktags, your script should be enqueued as dependent
+ * on "quicktags" and outputted in the footer. If you are echoing JS directly from PHP,
+ * use add_action( 'admin_print_footer_scripts', 'output_my_js', 100 ) or add_action( 'wp_footer', 'output_my_js', 100 )
+ *
+ * Minimum required to add a button that calls an external function:
+ * QTags.addButton( 'my_id', 'my button', my_callback );
+ * function my_callback() { alert('yeah!'); }
+ *
+ * Minimum required to add a button that inserts a tag:
+ * QTags.addButton( 'my_id', 'my button', '<span>', '</span>' );
+ * QTags.addButton( 'my_id2', 'my button', '<br />' );
+ *
+ * @param string id Required. Button HTML ID
+ * @param string display Required. Button's value="..."
+ * @param string|function arg1 Required. Either a starting tag to be inserted like "<span>" or a callback that is executed when the button is clicked.
+ * @param string arg2 Optional. Ending tag like "</span>"
+ * @param string access_key Deprecated Not used
+ * @param string title Optional. Button's title="..."
+ * @param int priority Optional. Number representing the desired position of the button in the toolbar. 1 - 9 = first, 11 - 19 = second, 21 - 29 = third, etc.
+ * @param string instance Optional. Limit the button to a specific instance of Quicktags, add to all instances if not present.
+ * @param attr object Optional. Used to pass additional attributes. Currently supports `ariaLabel` and `ariaLabelClose` (for "close tag" state)
+ * @return mixed null or the button object that is needed for back-compat.
