A Technical Machine, or TM for short, is an item that is used to teach a Pokémon a move. TM set on Pokémon Brown has changed a bit from the one introduced on Pokémon Red/Blue, with 12 TMs changing the learning move. The game features 50 TMs and four HMs. As in Pokémon Red/Blue, a TM is a single-use item.
