Undo

This feature is used to Undo the last action performed. If multiple cells or an entire record(s) has been copy/pasted, the entire action is undone. To Undo several actions, press this button repeatedly.

NOTE: Some actions can't be undone, such as adding or deleting a column. If an action cannot be undone, the Undo button will appear inactive. Use Redo to cancel an Undo.
