I believe this should be a click. This will be easy for alternative input
devices.
If you are going to have multiple options like copy and move you might
consider a menu to selec the option.

The user may escape the move or copy and so it would be easier to leave
it there while you drag. It would be good to change the mouse pointer
during th emove.

Not sure what you mean by 'previewing.'
