        A reference to the slide in this presentation that is the target of

        `PP_ACTION.FIRST_SLIDE`, `LAST_SLIDE`, `NEXT_SLIDE`,
        `PREVIOUS_SLIDE`, and `NAMED_SLIDE`. Returns |None| for all other
        actions. In particular, the `LAST_SLIDE_VIEWED` action and the `PLAY`
        (start other presentation) actions are not supported.

        A slide object may be assigned to this property, which makes the
        shape an "internal hyperlink" to the assigened slide::

        Assigning |None| removes any slide jump action. Note that this is
        accomplished by removing any action present (such as a hyperlink),
        without first checking that it is a slide jump action.
