Transition Buttons
The transition buttons allow you to select what is included in the next transition, what type of transition is to be performed, and perform the transition. These buttons function similarly to the buttons in the Transition Area on the control panel.
Tip: The Transition Buttons on ViewControl only control the transition area of ME 2. To control ME 1 you can create a custom control to perform the effect you want
and assign it to one of the custom control buttons.
