Studio move group of vertices.

[Baha Hijazi]

Hi, I'm using graphwalker for the first time, and I'm not sure if I'm doing it right but my model is growing so I tried to move a group of vertices in one go and I noticed pressing ctrl or shift while moving the mouse I can select multiple vertices but when I move them only one is moved and the rest go back to the initial position. I can try to attach a gif if needed.

Thanks!

I didn't find in the docs info about how to use studio (I meanly write json model and import but it's useful to move the nodes after import) so also I don't know if there's a way to undo action.
