I'm still fairly new at using the Creation Kit, but I figured others may be interested and want to jump in. All of what I posted is pretty much covered in the first Creation Kit video released by Bethesda. I might be able to answer some questions and I'm definitly looking for some help myself.
I'll throw out some to start :D
Shift + Q will allow you to click on an object to set the grid to that object. Makes connecting angled objects easier. Shift + Q then click on the void to reset it.
z + left click will move objects up and down only (along the z axis)
x + left click will move objects left and right only (along the x axis)
y + left click will move objects forward and backward (along the y)
pressing T while an object is selected will center the object with a top down view
P.S. If you know how to create animated water definitly post!
