Every [[Limit (category theory)|limit]] and colimit provides an example for a simple natural transformation, as a [[cone (category theory)|cone]] amounts to a natural transformation with the [[diagonal functor]] as ___domain. Indeed, if limits and colimits are defined directly in terms of their [[universal property]], they are universal morphisms in a functor category.
