If you’re using the Eraser tool (there are rare occasions when it’s preferable to using layer masks), and you get a little excited and need to bring back some of the image you just erased, your only option is to undo, right? That can be problematic if you’ve done a lot of work without letting go of the mouse. (Extra Tip: Let go of the mouse often while painting or erasing.) Try this instead: In the History panel (Window>History) click in the box to the left of the previous state just above the Eraser state, which should be at the end of the list. Hold down the Option (PC: Alt) key, and paint. Whoa! Yeah, the eraser is now working like a History Brush and painting back where you’d previously erased. Who knew?
