ReadyAPI Groovy script debugger - How to inspect ReadyAPI variables?

A groovy script in ReadyAPI references ReadyAPI variables like "context". For example, like this - String scriptVar = context.expand( '${#TestCase#myVariable}' ). I would like to inspect the variables inside "context" before they are "expanded" by the script and assigned to variables like scriptVar. How do I do that while debugging ?

In the debugger variables, I expanded the "context" variable to show all its internal variables. But, I could not find any obvious place where all its variables like myVariable would be stored.
