Space Bar Astronauts

Originally (on early writers dating back to the late 19th century) the “bar” was literally a metal bar running across the full width of the keyboard (or even wider, and even surrounding it) that triggered the carriage advance without also firing any of the typebars towards the platen. Later examples gradually shrank and developed into their current more ergonomic form as a wide, centrally located but otherwise apparently normal “key”, as typewriter (and computer) keyboards began to incorporate additional function keys and were more deliberately “styled”. Although it varies by keyboard type, the space bar usually lies between the Alt keys (or Command keys on Macintosh keyboards) and below the letter keys: C, V, B, N and M on a standard QWERTY keyboard.
