Moving Nodes in the Graph Node Editor Panel
To move any type of node in the Graph View, use your cursor to click and hold the node, then drag it to where you want to move it. You must position your cursor over either the title line of the node or in empty blank space of the body of the node that is not part of any property configuration area.
If you drag a node to the right, left, up, or down out of the currently visible Graph View, the Graph View should travel to allow you to keep dragging the node further in that direction.
