SQL Developer Shortcuts
===

I am using SQL Developer to connect to an Oracle DB.

I would like to be able to see the constraints of a table via the command window. Usually I have to navigate the tables tree and then open the table details. Is there a shortcut to allow me to access the constraints (in particular the FK constraints) by writing a command? Ideally I want something like 

    desc table_name

where desc describes the table. I know desc is SQL based but are there any commands I can use within SQL developer?

Thanks in advance.
