In my opinion the key-combination shift-delete is not working as it supposed to be.
When I delete an item with only delete-key, I first get a confirmationscreen and when I press 'yes' the item moves to recycle bin.
When I delete an item with shift-delete-combination, the item is removed directly without confirmationscreen and bypassing the recycle bin. I think this is a little risky. Shift-delete should work like in windows explorer, first a confirmationscreen and when pressing 'yes' the item is deleted directly, bypassing the recycle bin.
