Selecting grouped nodes by dragging

 

To select a group of nodes by dragging:

1. Place the pointer over a clear area of the canvas above and to the left of the group of nodes you want to select.
2. Press the left mouse button and drag down and to the right around the group.

   A rectangle appears, enclosing the nodes you want to select.

3. Release the mouse button.

   Any nodes that are either completely or partly inside the selection rectangle become selected.
