So with G I can move an object up a little and with F I can force the object to place itself to the ground, but is there any key for lowering an object like G does except forcing it to go below the landscape?

I know I can edit the object and change it's landscape position to go down but it's so slow and I was hoping there'd be an easier alternative.

Really?
No respond?
It's been two weeks...

Again, is there any anthesesis to the G key when I have marked an object?

It's been a ghost town in here since Skyrim was released. Z raises and lowers an item so just hold Z and drag it under the landscape.

Danke sch?n.
