  Hold on a second ... according to Tog, which is faster? He seems to be
arguing out both sides of his mouth here. First he says the mouse is
faster, then the keyboard. It can't be both. And was Apple testing people
who *could* type, or *couldn't*?

  And if this was in the 80s, then that was with Apple keyboards that didn't
have a numeric keypad/editing pad, or (on the later keyboards) the separate
editing keys *and* the numeric keypad.

  -spc (But there's a reason why Raskin's ``Find'' function was 50 times
        faster ... )
