Creating an ER diagram

If I had the names of 10 tables in a list in the editor, how could I generate an ER diagram?

As I understand from the Schema Browser I can select tables and generate an ER diagram from them or within the ER Diagram I can add the tables I want. But is it possible to have a list and get an ER diagram.

The best way to do this is to use the object palltete (main menu - view - object pallete). Then uyou can quickly drag-drop what you want into the ER diagrammer.
