## Undo/Redo

Any action performed in an iTool window can be undone or redone. The Undo and Redo mechanism provides a useful way of retracing and repeating steps that have been performed in the iTool window.

Note Operations which cannot be undone are Open, Save, Export, Export variable, Print, Exit, and window moving and resizing.

To undo the most recent action, do one of the following:

- Select Edit Undo

- Click

To undo multiple actions, simply repeat these commands. When no more actions remain to be undone, the Undo menu item or toolbar button is no longer active.

To repeat actions that have been undone, do one of the following:

- Select Edit Redo

- Click

Tip Look at the text following the Undo or Redo menu item, or hover the mouse pointer over the Undo or Redo button on the toolbar to display the tooltip, to identify the action that will be undone or redone.
