This made me curious. Apparently this part of the machine was called the "compensation tube". But it's much more elegant than you've said. When you press 2 keys in quick succession, the 2nd key press is "saved" temporarily by latching a spring, so that as soon as the 1st key is done, the 2nd key is struck. It's essentially a 1 character buffer, which is apparently sufficient to give a very fluid typing feel. https://www.youtube.com/watch?v=xuPduBVGf8g https://www.youtube.com/watch?v=xuPduBVGf8g http://www.bitsavers.org/pdf/ibm/typewriter/selectric/CE_instructionManual.pdf http://www.bitsavers.org/pdf/ibm/typewriter/selectric/CE_ins...
