The correct name is carriage return lever ("Wagenrücklaufhebel")
which _also_ performed the line feed, (t. t.) line switching
("Zeilenschaltung"). An additional little lever would control
by how many steps this would be: 1/2 line, 1 line, 1+1/2 line,
sometimes also 2 or 3 lines, and often a position in which
line feeds were inhibited, possibly for multi-type purposes.
The horizontal movement of the lever against the carriage
would do the line feed part, and then you would use the lever
to move the whole carriage against the typewriter, working
against the power of a spring-and-string mechanism (which
moves the carriage when you press the keys).

Many , but not all.
Very "strange" typewriter keys are "✧" (star) for HERE IS,
invoking the teletype's own identification sender, and
also "✠" (black cross) for WHO'S THERE?, in German "Wer da?")
to request that identification from the other partner on line.

The tabulator key would advance horizontally to mechanically
preprogrammed positions (or fixed ones, not chanceable by the
typist), and some typewriters had (t. t. )decimal tabulators
that would allow you to easily reach decimal positions
representing thousands or millions.

Some typewriters would have a T-shaped line feed lever which
advanced the paper by 5 or more lines, but it's primary purpose
was as an load / unload lever so you didn't have to rotate the
knobs for manual vertical control.
The process of advancing the paper was... advance ("Vorschub",
"Blattvorschub"), so yes, line feed had a term, but it was not
the same as on the teletype, it simply was "advance the paper".
As mentioned, teletypes had distinct keys "<" for carriage
return and "≡" for line feed, and when they also had "↩", you
could press that one key and get "<≡" or "≡<" generated. I'd
have to check on the papertape representation in which order
it actually happens - happen_s_ - tempus praesens... ;-)
