What is another name for caps Lock key?

Answer 1

The another name for the caps lock key is shift lock key. When typewriters were first invented there was no standard arrangement of the letters on the keys. Originally, it made a lot of sense: in a mechanical typewriter the Shift keys did just that: they shifted the type mechanism vertically so the type bars would hit the paper with the uppercase letters; and the Shift Lock key would keep the keys locked in this position. This key had to sit right above the Shift key, because it physically latched it in a depressed position; hitting Shift again would release the lock. It was very easy to see (and feel) whether Shift was locked or not, because both keys would be depressed when the lock was engaged. Early computer keyboards carried this idea forward, with a Shift Lock or Caps Lock key that had two physical positions: depressed for Lock, and flush with the other keys when released. Later, as keyboard makers sacrificed quality for cheap manufacturing, the more complex and different two-state key was replaced with a momentary key called Caps Lock or Shif Lock key.

I don't see manufacturers giving us back the 2-position key (it would cost them a few cents, after all), but the least you may be unaware that depressing Shift+F3 repeatedly will change any selected text to lowercase, uppercase, and sentence case.
