I have studied this tutorial https://www.youtube.com/watch?v=GtTeltGpOPg
and at 10.35 - 10.40 components are moved into the pink box, sadly though
it is not explained how you actually select them or move them.
I have tried a blue outline that encompasses the design and copy
a paste just duplicates what is being moved which ends up a mess
so matter of starting again.
can it be explained how to select the components and move them to the pink box
as the video shows please
Brand new interactions and interfaces. 
Easy to use and quick to get started.
