When adding/editing multiple instances of a component, Individual Control enables you to have individual control over the parameters of each instance.
At any time (while in creation or in edit mode), parameters values changed under Individual Control can be reverted to their original values (at the time of the Add operation), by using the Reset Individual button.
Example:
The highlighted cap screw is an instance whose parameters have been changed under Individual Control. These parameters are highlighted (boxed) in a color defined in the Preferences (Modeling/Color/Add_Operation); in the example below, the changed parameter highlight color is blue.

Press the Reset Individual button to reset the original parameter values. At this stage, the Reset Individual button is grayed out.
