Autoreport keyI think there should be an autoreport key.
I would place it on [R] - for [R]eport or [ U] - many games use this button for autoreport.
When you press it, you will say (for instance):
X= [000] Y= [-111] (Alfa outpost - Entrance)
or
X= [-010] Y= [123] (-Field-)
or
X= [-900] Y= [100] (Main base - Kitchen)
