Hi Tom,
Please go to ezEdit and under Display tab you'll see the property Session Name. Please pick a name of that value at your convenience (please note that the name is case sensitive) and complete the qSelector configuration (Liust Name, Dsiplay fields, etc).
Now, you can access this session value from other webparts (ie qListView and use it to filter the list based on the qSelector session value).
If you still have questions please let me know.
