Abstract
Editing operations are monitored for operations for which information must be stored in order to properly apply an undo or undo/redo sequence to plurality of files. A snapshot is taken and persisted before such an operation is performed. Upon the execution of an undo or redo command, the persisted snapshot is retrieved and applied to the newly generated editing element.
