+               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
+               that (again with aForward=true) will select the first one-off.
+               Likewise if decrementing the index when the first one-off is
+               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

+               that should be ignored, depending on the consumer.  That's true

+               When the last list item is selected and the user presses Down,

+               restored to the value that the user typed.  Pass that value here.
