Cottage Return was the name of the handle on the typewriter. 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). > Everything else is from teletype machines. 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. > There was th "Horizontal tab" on a typewriter, it was just > a 'tab' and there was certainly not vertical tab. 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. > There was no 'line feed' because you didn't have a term for > 'turn the roller by hand'. 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... ;-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
