I only see this effect over network connections when I hold down and
repeat an arrow key. An arrow key acctually produces several
characters. Try doing,

  <ctrl-v><up-arrow>
  ^[[A

I believe that's an ESC followed by '[' and 'A.' Now you see where the
'A's come from? =) (Try the others to find the 'B.') That is, vi(1)
loses the association of that group of characters actually being one
keyboard event.

Of course, the way to prevent this is to use h-j-k-l to move around
the vi screen.
