It has a handle for turning the paper from time to time when you are tying. It has a place called type bar which has the printed letters over it.

In 1875, Amos Densmore and Christopher Sholes rearranged the typewriter keyboard so that the letter would not be so close together and the type bars would be at the opposite direction.
