There are two options for copy nodes in the workspace:

The first method to copy selected nodes involves using the keyboard shortcut Ctrl (or Cmd on Mac) + C. To paste the copied nodes, use the shortcut Ctrl (or Cmd on Mac) + V.

It’s important to note that when a node is copied, its connections are also retained in the new, duplicated node.

The second method for copying involves using the left mouse button in combination with the Alt key. To execute this, click and hold the left mouse button on a node or a selected area. Then, press and hold the Alt key while dragging the nodes to a new location. This action copies the nodes, and upon releasing the mouse button, the copied nodes will be inserted at the chosen location.
