This collection-/tableview technique is known by maybe 0.1% of users and used by much less. You can also alt-arrow(?) to move the cursor around and select more elements with space. Never seen anyone use that. Instead of clinging onto this cursor nonsense they’d better finally made it work as (no selection, arrows select next/prev, [modifier+]mouse selects as usual) and get rid of a cursor. And make a proper tree view. Everyone does it this way except explorer.
