when going back in menu selection items with a list of items, it always go to the first item of the choices list: for example if begins at item1
+1 -> item2
+1 -> item3
+1 -> item4
-1 -> item1
+1 -> item2 ...

issue fixed by commit befb06b.

It was due to a fixed increment, but this fix implies that a control is done by the '<' and '>' chars to navigate the choices
