World editor keyboard shortcuts

Is there a listing of the world editor keyboard shortcuts around? Also, when moving asset pieces and trying to snap them together, I notice they “jump” around alot making it very frustrating to add, say, ramparts to a fortress wall. Is there an easier way to do this? In other world editors you could use the arrow keys to slightly move the asset in the right direction. Is there anything like this for the Grim Dawn world editor? Any advice is appreciated!

Here is the tutorial for TQ modding, maybe it will help if the official GD tutorial didn’t cover any of this:
