It's not a cheat and like DJ says its neccesity in FF2 to do things u normally wouldn't

in a regular RPG like attack ur self and heal on the next turn, or casting a spell that is

bound to fail in order to level it up so it might just work. Swap has no true

meaningexept for brains to use it and for u to use it and jack up ur skill. I'm impacient

so the select-cancel trick never caught on with me.
