Pressing means keeping the stylus pressed in one place. Click, hold, but don't move.
Scratching is pretty hard to do. Rapidly move the stylus up and down/left and right in a small area. It has worked for me, though not regularly. No$ still has some problems with too rapid motion.

TWEWY only works using the zoom apps without gamebreaking video errors.
Scratching and shouting into the mic are the two most tedious means of attack; I just put them in into unnessessary slots or use shutdown PPs. I'm not sure whether any scratch pin needs fight PP to evolve.
