'copy with url': what does it do?

[cnewtonne]

I often have this need to insert a link to in item that displays the whole lineage instead of just the item title. There could be multiple items with the same name, but in different locations. This helps me differentiate between them. So I played with this feature to 'copy with url', but I did not see it behave any different from 'copy'. So ...

1) what does it do?
2) is there a way to insert a link in the editor to display the lineage path?

Thank you.
