   8 [ Upstream commit 52d2c7bf7c90217fbe875d2d76f310979c48eb83 ]
   9
  10 The CapsLock key on Atari keyboards is not a toggle, it does send the
  11 normal make and break scancodes.
  12
  13 Drop the CapsLock toggle handling code, which did cause the CapsLock
  14 key to merely act as a Shift key.
