Undoing Actions

---

To undo the last action performed:

• From the Edit menu, choose Undo .

The last action performed is reversed. The Redo command changes to reflect the undone action. The Undo command changes to reflect the next action you can undo.

For example, if you draw cyclohexane, create an atom label text box, type a label, and select and rotate the structure, you will be able to remove the actions as follows:

1. Remove the rotation.

2. Remove atom label.

3. Remove the ring.

At each step, the text of the Undo command indicates the action being removed.
