Almost all RoadRunner operations can be undone or redone. RoadRunner has an infinite undo stack, which enables undo and redo of almost all operations performed in the 2D Edit Window and 3D Edit Window. Many operations elsewhere in the RoadRunner interface also have undo and redo support.
Most operations performed in the Library Browser (such as deleting or renaming assets) do not have undo and redo support.
The undo stack is related to the current scene. Operations that change the current scene (such as loading a scene or creating a new scene) will remove all actions from the undo stack.
If there are no remaining operations to undo (or redo), an error message is displayed in the Status Bar.
Select the Edit > Undo option in the Menu Bar, or press Ctrl+Z.
Select the Edit > Redo option in the Menu Bar, or press Ctrl+Y.
