Abstract: A method and system for restoring, to a previous state, a single object whose state was modified in a group editing action wherein a plurality of objects, including the single object, were modified as a group. Prior to execution of the group editing action, restorative information, necessary to restore each of the objects to its state prior to being modified by the group editing action, is stored in a data structure. After execution of the group editing action, group edit restorative information indicating the state, after the execution of the group editing action, of each of the objects that were modified by the group editing action is stored in another data structure. The single object is restored to its previous state in accordance with the group edit restorative information corresponding to the single object, in response to an indication that one of the plurality of objects is to be restored to its previous state.
