The Undo icon allows you to undo your last action. The Redo icon allows you to redo the action. The Redo icon is the opposite of the Undo icon. It reinstates the change made by the Undo icon.

The Undo icon or Redo icon is enabled (blue) when there is an action to undo or redo. Otherwise, the icon is disabled (gray).

For example, assume that your first action when creating a report query is to add a database field to the query. After you add the field, the Undo icon turns blue. You can now click the Undo icon to remove the field from the query. The Undo icon turns gray, and the Redo icon turns blue. To restore the field to the query, click the blue Redo icon.

You can also press Ctrl+Z to undo an action, or Ctrl+Y to redo that action.

You can undo and redo up to 25 actions per session. InfoAssist maintains the undo/redo list of actions even when you switch between queries.

When a dialog box is open in the application window, you cannot use the Undo and Redo icons. However, when you click OK and close the dialog box, the icons become available for use. With a single click of Undo, you can undo all the actions that you performed in the dialog box, and you can reinstate them with a single click of Redo.
