Using Navicat to create a Key on 2 column
===

I can create a Primary Key using Navicat in the `Design Table` section of the software. However, I cannot seem to create a key on 2 columns, which in MySQL statements will be something like

    CREATE TABLE casting(movieid INTEGER,
                     actorid INTEGER,
                     PRIMARY KEY (movieid, actorid)
                     )

Can it be done using the GUI in Navicat? Or must I write the query manually and run it.
