Once working in the Radial Filter, we have the option of expanding or subtracting from the Radial Filter mask, as you are aware. Is there a shortcut to bring up the Brush when working in the Radial Filter? I do know that once the Radial Filter's Brush accessory is chosen, when can Option to move the Brush to subtractive, and releasing Option restores the Brush's additive role. But must we manually click Brush to have this option?
Many thanks,
