What is a Pokemon TM modifier for Action Replay?

A TM modifier is a code that will change a certain TM number to a different move that was not a TM. You use it for teaching moves to Pokemon that can't normally use that move. For instance you activate a code for Shadow Force TM#01 it will change TM #01 which is Focus Punch into Shadow Force! It is only of use if the code changes a TM than can be learned by ANY Pokemon.
