I often make a duplicate copy of an item (file or folder) and work on it, for modifications that I will intentionally throw away.

Using keyboard shortcuts to duplicate an item leaves the keyboard focus on the original item instead of shifting it to the new item. This means that successive operations without watching the screen will work on the wrong target.

This means that some operations following the copy (Enter to open, Ctrl-I) will operate on the newly created item, though a rapid keyboard navigation + an operation will take action on an unexpected item.

Worse, try moving the selection with arrow keys during a longer copy process. Upon completion of the copy, the selection will jump to the newly created duplicate, but the keyboard focus will stay on whatever item you happened to be on at that moment.

1. List view in browser window
2. Select an folder ("foo")
3. Ctrl-C to copy, Ctrl-V
4. (optional) move selection with arrow jeys during copy operation

Actual:
Newly item ("foo (copy)") is selected, original item ("foo") has keyboard focus. If (4), some other item will have keyboard focus.

Pressing down arrow will select the newly created item, instead of the one following it. Pressing up arrow will select the item preceding the original item instead of the original item.

If (4), predictable (according to how keyboard focus moves) but unexpected (according to which item has the more visible selection drawn) results: some other item will get selection and focus, but it isn't obvious which one unless the user actually looks for keyboard focus before pressing the arrow keys.

Expected:
New item ("foo (copy)") has both selection and keyboard focus in all cases.

Pressing down arrow will select the item following the newly created item. Pressing up arrow will select the the original item.
