This mode cancels last made on a map operation of creation, editing or deleting. The cancellation of operations is made sequentially, since last (it is impossible to cancel second to last operation, not having cancelled last). The information about made on a map editing operations is stored in the transaction log, therefore cancellation of last operation is possible and after exit and restart of a system. The cancellation of operations is possible before execution of a map sheet sorting. Process of map editing, as a result of which one some objects change at once (adjustment, merge, operation above selected objects), is one operation. Therefore as a result of its cancellation all objects which have exposed to editing during execution of this operation will be restored.
