There are many App_List<something> functions available but somehow i can not find the way to list certain detail

Like finding subelements (finding udt-functions is pretty easy since part of the name is functions name and functions can be listed
but for module classes that does not work.

Can i retrieve somehow a list of methods that are defined for a module class? And a list of property-names or datatype of properties?
Is it maybe hidden in thinair- i some cases it can list subelements of variables that are dimensioned as class variables so it must somehow
find the information in the module or in the autocomplete-info

How could one list the udt-definition - which were probably easier than requesting names and types from udt-elements one by one
