The )show system command is used to display information about types or partial types. For example, )show Integer will show information about Integer .
Domain is not the name of a known type constructor. If you want to see information about any operations named Domain , issue )display operations Domain

For example:

There are no library operations named reify Use HyperDoc Browse or issue )what op reify to learn if there is any operation containing " reify " in its name.
Cannot find a definition or applicable library operation named reify with argument type(s) Type
Perhaps you should use "@" to indicate the required return type, or "$" to specify which version of the function you need.
