Clip Masking in Shadowbox

I brand new to zBrush. I have been following along the Shadow Box tutorial where the teacher is drawing a turret for a tank. I can draw my basic shape in shadowbox and it appears. When it comes time to clip it and whittle it down into desirable shapes, my clip does not “whittle down” but rather creates extra clay in shadowbox by placing it next to my base turret shape. Please someone tell me how to make it clip rather add more clay. Thank you.

Thanks Doug. The ALT key subtracts from the mask giving me the effect I was looking for. I just could have sworn the teacher in the tutorial was using the clip curve brush by pressing CTRL + SHIFT. When I used the clip curve it impacted the shadow box mesh vs. the target mesh being developed thus causing me to raise concern. So thank again. I will review tutorial again to see exact brush the teacher uses.

Glad it helped.
