As I read AP Help and watched several tutorials, entering the J keyboard key repeatedly is programed to scroll through the Healing Brush and all brushes hidden within that group. My problem is I can enter J and it will scroll to next brush; however, if I enter J again, no scrolling, my macOS chimes as invalid command or no option and a new brush will not be selected from the group. Attaching info to clarify my problem and brush group.
