The title pretty much states my problem. I consider only finitely generated exterior algebras $\bigwedge V$. It is known that any morphism between exterior algebras y determined by its action on generators, i.e. its action on $V$. Does anyone know a good example of this kind of morphisms?

By $\mathbb{Z}_2$ graded I mean a morphism of algebras such that the parity of the degree of a form $\eta$ is preserved by such a morphism; and by $\mathbb{Z}$ graded I mean a morphism that preserves the grade of $\eta$, i.e. if $\eta$ is a $k$-form, then so is $f(\eta)$ where $f$ is the morphism in question. Thanks in advance.
