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.

I would hate if Microsoft "fix" it because it has been this way since at least Win 98 and is what I am used to.

What percent of users navigate explorer with a keyboard at all? I'd hate to lose keyboard selection over this. Ctrl and shift do different things and I use them both.

I do this all the time.

Every once in a while, navigating with the keyboard in Explorer will cause the window thread to hang up in a busy loop and I have to kill it. I have no idea if this is an Explorer bug or caused by other stuff.
