Manually linking one node to multiple others

Someone asked support@paterva.com: "It is very tedious to put five thousand arrows of emails to a single identity. Is there any way to make this easier?" There is indeed an easier way and I thought I'd put the recipe out here on the blog:

Follow these easy steps to link many nodes to a single node:

1. Select the many nodes.
2. Move the mouse pointer so that it hovers over the single node, but don't select it.
3. Left click on the single node AND hold the left click button in.
4. Drag a line to any of the many nodes.

The single node will now be linked to the many nodes with multiple links, but the link direction must be inverted.

We now need to select all these links and invert their direction. To do this:

1. Select the single node.
2. On the ribbon go to Investigate -> Select links -> Outgoing. You can also do this by holding control and dragging a box around the links.
3. On the ribbon - Investigate -> Reverse Links.
4. Voila!
