Hi,
Every time when I ⌥ ⌘ \ (the default shortcut to Show list of available Actions for selected Finder item), the file which I selected has been copied too.(Yes, the file was copied).
When I change the shortcut to another, same problem also exist.
This is the problem I have found since Alfred v2 - v2.8.3 (Now I'm using v2.8.3(435))
