To Undo the Last Operation

Do one of the following:

On the Quick Access Toolbar, click Undo.

Press <Ctrl+Z>.

Note: For example, suppose that you just deleted an element with the Delete Element tool. To undo this operation, you would click the Undo icon on the Quick Access Toolbar.

Tip: If you hover the mouse over the Undo icon in the Quick Access Toolbar, it shows you the last command it will undo.

Tip: After you undo an operation, the operation just before it becomes reversible. You can, therefore, undo a series of operations by repeatedly clicking the Undo icon.

Note: There is no limit to the number of undo's you can perform within a design session. The undo buffer is only limited by your disk storage space.
