I was watching this vid:

I'd like to know how to a) make terrain transparent (1:16) and b) move the camera view independently of my body (1:53)

As Server Admin

Enter the console command

debugcamera

for an out of body experience

F1 Console Tools then untick terrain. The terrain becomes transparent. You can bind this operation to key also.

Fabulous thanks!

... OK I've googled but I give in, how to you bind the tools/layers?

layer.toggle LayerName
