ActiveButtonState is one of the elements of the state table governing the behaviour of the finite state machine within an ActiveButtonControl. For each controlled button, it holds the index of the label to be displayed in this state, whether that button should be enabled or disabled and which state should be jumped to if that button is pressed. See the example documented in ActiveButtonControl.
