trying to used the healing tool but it says Option-click

There are two Healing Brushes:

• Spot Healing Brush Tool
• Healing Brush Tool

The Spot Healing Brush tool quickly removes blemishes and other imperfections in your photos. The Spot Healing Brush works similarly to the Healing Brush: it paints with sampled pixels from an image or pattern and matches the texture, lighting, transparency, and shading of the sampled pixels to the pixels being healed. Unlike the Healing Brush, the Spot Healing Brush doesn’t require you to specify a sample spot. The Spot Healing Brush automatically samples from around the retouched area; the Healing Brush requires that you set a sampling point with an Opt click.
