SET allows to change properties of Objects, Objectives and current view.
After you select the Object, list of States will be repopulated with existing Object's States.
Some basic parameters of the Object could be changed. It is important to understand, that the changes are applied to Object's container.
Selected Master-Slide will replace current Master-Slide of the Slide.
Score in selected Objective will be changed.

It is used to differ scores from different task in objective's score "heap".
