+This [Action.md] is used to output the material properties computed by a [Material](syntax/Materials/index.md)
+or a [FunctorMaterial](syntax/FunctorMaterials/index.md) to an auxiliary variable.
+Vector, tensor, and array-valued properties can be output to variables prefixed with the component or index.
