Various technologies and techniques are disclosed that allow an eraser to be used for additional operations. A pen feature is provided that supports various eraser gestures. An eraser gesture is detected from a pen input device. If the eraser gesture matches a supported eraser gesture, then an operation associated with the supported eraser gesture is performed. For example, a scratchout gesture made with the eraser can undo a previous erasure of text made by the eraser. A customization feature is provided that allows a user to customize some or all of the eraser gestures.
