[Uml-user] use case "step into"

[Wolfram Kriesing]

first of all (me too) your program is great. UML easy to use, keep up 
the spirit

my problem/question is that i created a use case which i want to 
specify more in detail. is there some kind of "step into". which works 
like double clicking a use-case and getting a level deeper into it?
