Video demonstrating flexible parts in LDCad

With the official launch of Spike Prime set, I was asked how to create cables in models... so I made this short video:

This is really helpful, thanks for posting it.  

There's something that happens around 2:08 where you generate a new guide point (sorry if that's not the right terminology) and then move it into the part to guide the cable.  How does that happen?  Seems like a keyboard command?  

Thanks,
