Holding the Option (Mac) / Alt (Win) with the Eraser tool will erase with history. Note: when Photoshop opens a document, it takes (by default) a snapshot of the document that appears at the top of the History panel – this is the “history” that the Eraser paints with. To change the “History” state that the Eraser uses to paint from, click in any empty well to the left of the desired state in the History panel. Both states (the one chosen to “erase” with and the one that’s being “erased” upon) must have corresponding layers.
