With the UNDO function, changes can be wound back. If you selected the function to select/move points and then shifted several points, the shifting of the points can be cancelled by the UNDO function. To do this, click on the lifebuoy icon for UNDO. The shifted points are then returned to their original positions. Repeated clicking of the lifebuoy icon will shift the points back and forth between their original and shifted positions.
The Undo function can also be called with the [Undo]-key of the Atari keyboard. On PC keyboard, this is usually [F12].
