Okay you may want to view some controls that help you PAN the camra around in the Cell View window, the main window you use to edit your world, To pan your camra use...
HOLD down SPACE to pan it left and right, or on the X and Y axis
HOLD down Z to only pan the Camra up and down, or Pan only on the Z axis
HOLD down Shift to look around and get a better view of things.
T will position the camra over a selected object.
Okay now to move stuff...
If you want to move stuff you need to...
HOLD Z to move the object on the Z axis, (Up and Down)
HOLD X to Move the object on the X axis, (Either left or right only)
HOLD Y to move the object on the y axis, (Either left or right only)
Now you can drag your object by not having to hold X or Y down, but to move it Up and Down, Hold Z. To Set and object on a serface or anther object, simply select the object and press F. That will drop the object on what ever its over. WARNING! DO NOT press F if there is nothing under it but plain sky. It will fall until it can't fall anymore.
There. That should give you a kick start for TES CS
Good Luck
