Issue:
UNDO is useful to cancel the mistake and go back to the right state, we can use Ctrl+Z or command UNDO to make it work. But sometimes you might overuse it and want to go back to a special step, how?
Solution:
Input command MREDO and then input the step that you want to restore. This command is used to reverse the effects of several previous UNDO or U commands. Besides, you can also use Ctrl+Y to go back step by step.
