TypeScript propertyof

I know TypeScript has a keyof keyword which yields the type of permitted property names for a given type. Is there also something like a propertyof which will get me the values of the keys of a given type? Specifically, I am wondering if there is a shorter way of doing

type Propertyof<T> = T[keyof T]

The way you discovered is the way to get the property value types:

type Propertyof<T> = T[keyof T]

There is no reason to have more features in the language then necessary, propertyof T would not be shorter, in fact as jcalz points out it is actually 2 characters longer.
