Copying and pasting nodes
Right clicking on a node in your model will give you a few options. Here, you can copy the current node and its contents by [Right click > Copy current node]
or pressing [Control + Alt + C]
(see shortcuts) while you select the right node.

You can insert these nodes wherever you want in the model. Select where you want to insert the copied node, press [Control + Alt + V]
, or [Right click + Paste node]
, and you have inserted your copied node.

The Berkeley Studio will automatically create a new connection from and to the node you pasted. If you paste a node at the edge of a model, it will only create one connection. If you don’t need the connections created by the Studio, you can delete them manually.
