Undoing and redoing changes


    You can use the Undo command to correct mistakes you make while using the Adobe Illustrator program. You can even undo an operation after you choose the Save command (but not if you have closed and then reopened the file). If an operation cannot be undone, the Undo command is dimmed.

    Depending on how much memory is available, you can undo an unlimited number of the last operations you performed, in reverse order, by repeatedly choosing the Undo command.

    You can also revert a file to the version that was last saved (but not if you have closed and then reopened the file).

To undo or redo an operation:

    Choose Edit > Undo or Edit > Redo. (Depending on the memory available to your system, you can choose Undo an unlimited number of times.)

To revert a file to the last saved version:

    Choose File > Revert. You cannot undo this action.
