At least some (Royals I think) there was a lever on the right that you would operate for CR (carriage return) and line feed. Pull a little bit to the left, and it would feed a single line, pull the remainder, and it would return the carriage, so you could just do a couple of short pulls and advance a couple of lines more precisely than yanking the paper.
It was decades later that they got a RETURN key (what they call Enter nowadays) that would do the LF/CR for you. Eventually there was a tape with white ink so when you backspaced, you could white out what you had mis-typed by mistyping it again! Before that, you would overtype a "/" and bull ahead. Or stop and (literally!) paint it over with a little brush.
The inventor of the little brush and the fast-drying paint became one of the first female business tycoons. (There were tycoons then, too. And impresarios. Dunno what happened to those.)
Bette Nesmith Graham indeed became a (minor) tycoon from Liquid Paper but died in her 50s.
Her son Michael was a member of the Monkees and Bette Nesmith Graham, produced Repo-man. I've met him; he's a nice guy.
I'm 31 and have used at least 2 typewriters in my life - obviously at no point did I need to for either school or work, but there's something romantic about them and I often fantasise about getting one to write with... though I'm fairly sure it would end up gathering dust as a (possibly pretentious-seeming) ornament in the corner of the room, so I avoid the impulse to buy one.
Just the idea of a portable. Almost but not quite like a portable piano in my mind.
