This history of Return / Enter / whatever it is on your keyboard is more fascinating and surprising than I expected. Worth reading:

> It was only when typewriters embraced electricity in the 1940s and 1950s that the carriage return completed its transformation into a key, and the distinctive lever could be detached.
I can't name a model off the top of my head, but I've def used typewriters that use a non-electric return key rather than lever. There was a spring that wants to push the carriage to the left. The action of normal typing compresses the spring, and the return key releases a latch releasing the spring.
