   For whatever mysterious reason, some of my code vanished into the ether -- 
I mean, where did the "end switch" go, for cryin' out loud!? Let's see if I 
can get it right this time...

on keydown thekey
  put thekey
  switch theKey
    case 1
      put "B" into OldPlay
      put "A" into NuPlay
    case 2
      put "A" into OldPlay
      put "B" into NuPlay
  end switch

  stop player OldPlay
  put the currentTime of player OldPlay into Atime
  hide player OldPlay
  set the currentTime of player NuPlay to Atime
  show player NuPlay
  start player NuPlay

  pass keyDown
end keydown

   Does *this* work better or worse than the original code?
