Select all / multiple nodes

Is it possible to select more than one node at a time if I want to rearrange my nodes?

Command-click on a Mac, probably control-click on PC

So I can command click nodes which creates a red highlight bar over the nodes, but I can't move them together?

I am wondering this as well. It would be good if you could lasso multiple nodes with a selection box.

+1 for the lasso and reposition of multiple nodes

I wish you could cut/copy/paste nodes like you could anything else. Adding lassoing, multiple moves, etc. would be good.

But at the top of my list would be keyboard commands for NEXT NODE and PREVIOUS NODE. We still don't have that after many, many years of asking for it. That should be right under the Node pulldown menu.

Yes. The only thing you can do with multiple nodes selected is to create a compound node (pp. 881-882 of the Resolve 12 Manual).
The stupid thing is that you cannot copy/paste compound nodes, which makes them about a half less convenient, as they can be.

+1 unless this has been solved since post creation
