How do I set the mini-hud reference object in DG3?

[Doug Beachy]

Hi all,

I am trying to figure out how to set the mini-hud reference object in the DeltaGlider III (this is the mini-hud with 5 modes
on the right side of the screen).

To be specific, I just left Earth en route to Venus and I am now orbiting the Sun.  I have set my main HUD reference object
to "Sun" (with CTRL-R) and that works fine.  The mini-hud, however, still references Earth (I can tell because I have been
watching it since I left Earth orbit).  The mini-hud does switch automatically to another planet/moon when I get close
enough, but I would like to be able to set it manually.  Does anyone know how to set the mini-hud reference object?  Thanks
for your help!
