I'm puzzled over this explanation in the User Guide:
I've tried shift clicking all around those colored lines under the equalizer, and I can't figure out if I'm missing the effect (what's supposed to happen?) or if I'm doing it wrong.When using the noise profile equalizer, use the color indicator to simplify the fine-tuning process. Colored lines of the indicator show: which sliders of the equalizer correspond to the colors of the selected image area/pixel (use the Shift key for pixel-wise indication);
