evaluates to act if a control that affects act is actively being used, and to norm otherwise.
- ControlActive can be used to switch between a faster computation to be done while controls like sliders are being moved, and a slower computation to be done once the controls are released.
- ControlActive[act,norm] can also be used to trigger evaluation of norm when controls are released.
- ControlActive is equivalent to ControlActive[True,False].
- ControlActive[act,norm] is effectively equivalent to If[$ControlActiveSetting,act,norm].
