ControlActive

ControlActive[act, norm]
evaluates to act if a control that affects act is actively being used, and to norm otherwise.

MORE INFORMATION

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].
