# Undo and redo actions in the flow designer in Amazon Connect
<a name="undo-redo-history"></a>

You can undo and redo actions in the flow designer. Choose the undo and redo items on the toolbar. Or, with your cursor on the flow designer canvas, use the shortcut keys: Ctrl\$1Z to undo, Ctrl\$1Y to redo. 

**Tip**  
On a Mac, Ctrl\$1Y opens the history page instead of performing a redo.

To access a history of your actions that you can undo, choose the **Undo** dropdown button on the toolbar, as shown in the following image.
