ContinuousAction

ContinuousAction
is an option for Manipulate, Slider, and related functions that specifies whether action should be taken continuously while controls are being moved.

Details Details

With ContinuousAction->True, continuous updates are supplied to Dynamic objects whenever the position of a control is changed.
With ContinuousAction->False, updates are supplied only when the controls are in their final position, say as determined by the release of a mouse button.
ContinuousAction->False typically gives the same behavior as Dynamic[expr, Temporary].
