docs: <p>Handles scrolling in response to a "home/end" shortcut press. This
  method will scroll the view to the top or bottom and give the focus
  to the topmost/bottommost component in the new visible area. If no
  component is a good candidate for focus, this scrollview reclaims the
  focus.</p>
  
  @param direction the scroll direction: {@link android.view.View#FOCUS_UP}
  to go the top of the view or
  {@link android.view.View#FOCUS_DOWN} to go the bottom
  @return true if the key event is consumed by this method, false otherwise
