Undoing and redoing in the designers
You can undo operations on a form or report. Once you undo an operation, the previous action is available to Undo.
You can undo and redo values that you set in the Inspector. Once you undo a value, the Undo command on the Edit menu becomes Redo.
To undo an operation, choose Edit|Undo (or press Ctrl+Z). To redo an operation, Choose Edit|Redo (or press Ctrl+Z).
