Before that, page-mode terminals used <Return> to move to first field on a subsequent line (like a line-based <Tab>) and sent the page only on <Enter> or <Fn-key>. This made for quick navigation w/ zero ambiguity.

Carriage return and line feed go way back. Tty stands for teletype. A computer was the job description of a person.

It’s turtles all the way down.
