I guess in terms of navigational help, could you perhaps add one or two special items, working much like the variety of ones you already have that gave temporary visual hints/assistance (added a temporary coloured light source at a random point within X distance of the key or provided a briefly visible glowing arrow pointing in the key's direction or something?)
