Here's one answer to my question:

on arrowKey tKey
  if tKey is in "right,down" then
    if number of the focusedObject < number of controls of this cd then
      focus on control (number of the focusedObject + 1)
    else focus on control 1 of this cd
  else
    if number of the focusedObject > 1 then
      focus on control (number of the focusedObject - 1)
    else focus on control (number of controls of this cd) of this cd
  end if
end arrowKey


But, it would still be nice to know why the original handler doesn't work:

> end tabKey
