From 3823486a5864796cd7fcba07521f4ca2ebab3885 Mon Sep 17 00:00:00 2001
From: Jonathan Gordon <rockbox@jdgordon.info>
Date: Thu, 7 Jun 2007 12:14:31 +0000
Subject: Add a mode the lists which doesnt show the selection marker. Useful
 for the debug menus where users shouldn't think pressing select would do
 anything.
