The AddContent(x, opts) calling sequence adds content to a previously constructed element.  This is an advanced feature.  No post-processing is performed. Therefore, shortcuts associated with the added element cannot be used.

The AddContent command must be used on constructed elements prior to a call to the Maplet command and can only be used directly on objects to which it is applied.
