ZBrush masking help

louiehamper

well i was just watching the tutorials on Zbrush and I got to the tutorial where they teach you masking and I cant seem to mask with alphas. Every time that I try and mask with an alpha, dragrect and a standard brush it changes to no alpha, freehanhand maskpen. I am pressing ctrl to mask and not sure what to do.

Are you choosing the alpha and stroke type while holding ctrl too?
