Cubik Studio

This should be a rather obvious thing, but I just can't figure it out.

How can I select and rotate/move multiple elements?

My guess was selecting one element pressing shift and adding another one to the selection, but that doesn't work out for me.
Also can't seem to find anything in the dropdown menus.

You have to hold right control then you can just click on multiple elements.

Sweet! Thanks, Geenium!

You can also draw a selection rectangle with Right Shift and left click in a 2D view
