	 * ## Working with QuickFix objects
	 *
	 * ### Adding controls to the QuickFix form
	 *
	 * Controls can be added in {@link #display} method using {@link CKEDITOR.plugins.a11ychecker.ViwerForm}
	 * methods.
	 *
	 * ### Executing the fix
	 *
	 * The fixing logic is placed in {@link #fix} method, so you need to simply call it when
	 * you're sure to apply the fix.
	 *
	 * @since 4.6.0
	 * @member CKEDITOR.plugins.a11ychecker.quickFix
