The whole point of having margins properly set up in a word processor is so the typist does not have to keep pushing enter. In fact, in this very comment box, I am not pushing enter and the cursor automatically moves from one line to the next.
The answer should be "false." When typing a paragraph, the lines will automatically wrap to the next line once the end of the line has been reached. It's true that you can insert a "hard return" by pressing Enter, but it is not necessary to press Enter in the middle of a paragraph to wrap to the next line of text.
