Touch means exactly how it sounds: Touching the stylus to the bottom DS screen. However, it is more akin to a 'tap', as the stylus need to be removed in order to keep the game from confusing a touch with a slash, drag, or press, depending on what you do after keeping the stylus in contact with the screen. Several psychs that utilize this touch-screen command are Apport and Force Rounds, among others.

This touch screen command is represented in the game with the icon . It is used to activate the following pin psychs:
