I just found out you can change what appears in the graphics using various keys, is there a page that lists these keys?

Type H for help in the graphic window.
Keys you need will appear.
You can try : 0 (zero), 2, R, T, B, M, U, S, P and Ctrl+Mouse to zoom

A - Rotate counter-clockwise
B - Headlight
D - Stop rotation
H - Toggle help menu gives you more
M - Toggles metric/non-metric
P - Precipiation map
R - Surface pressure map
S - Smoothed cloud map
T - Temperature map
U - Unsmoothed cloud map
X - Physical relief
Z - Rotate clockwise

0 - Toggle stars
1 - Toggle a list of contributors
2 - Toggle between cell view and smoothed view in temperature, pressure and precipitation displays (but not cloud - need to use the "S" and "U" keys)
3 - Political boundaries (red borders)
4 - Carl's favoured "Death Star" display :)
6 - Political boundaries (red borders)
7 - political boundaries (green borders)

Ctrl + left click + mouse up (or left) - zoom in
