-               This has a couple of effects, depending on whether there is
-               currently a selection.
-               (1) If true and the last one-off is currently selected,
-               incrementing the index will cause the selection to be cleared and
-               this method to return true.  Calling advanceSelection again after

-               selected, except in the opposite direction of course.
-               (2) If true and there currently is no selection, decrementing the
-               index will cause the last one-off to become selected and this
-               method to return true.  Only the aForward=false case is affected
-               because it is always the case that if aForward=true and there
-               currently is no selection, the first one-off becomes selected and
-               this method returns true.
-        @param aCycleEngines

-        This handles key presses specific to the one-off buttons like Tab and

-        are always used in conjunction with a list of some sort (in this.popup),

-        items and the one-off buttons.
-
-        @param event
-               The key event.
-        @param numListItems
-               The number of items in the list.  The reason that this is a
-               parameter at all is that the list may contain items at the end
-               that should be ignored, depending on the consumer.  That's true
-               for the urlbar for example.
-        @param allowEmptySelection
-               Pass true if it's OK that neither the list nor the one-off
-               buttons contains a selection.  Pass false if either the list or
-               the one-off buttons (or both) should always contain a selection.
-        @param textboxUserValue
-               When the last list item is selected and the user presses Down,
-               the first one-off becomes selected and the textbox value is
-               restored to the value that the user typed.  Pass that value here.
