Create virtual foreign key when pressing Ctrl during drag & drop

[ask9]

I suggest to add feature: if user press and don't release the Ctrl-key on a keyboard and drag & drop a column, the virtual foreign key is created (or the corresponding checkbox is set automatically). It will make it easier to create virtual FK (avoid additional click) especially when you have to create many-many virtual FK.
