Shift + I - Get Reference Data - What exactly is this used for?
Ctrl + M - Move References. Fully cut and paste references w/exact IDs. This doesn't appear to do anything.
P - Save Local Map Snapshot to Game\Data\Textures\Maps\. This doesn't appear to do anything either.
V - This is supposed to toggle leaves, but does not. Used in conjunction with the mouse, it does zoom in and out.
S - This is supposed to toggle Sound objects, but does not.
4 - This does something with the Frustrum, but I cannot tell what use it is.
0 - This toggles some kind of view, but again, I cannot tell what use it has.
F10 - Brings up the TES Construction Set Scene Graph window. What use is this?
Here is what I have so far. If you see anything that is missing, again, please let me know so I can update my file.
