How does one access a closure property in the watch window in the browser debugging tools?

If I’m sitting at a breakpoint in the Chrome debugger in some JavaScript code, I can see the value of one of the function parameters in the “Scope” section inside a Closure:

Is there anything I can type into the Watch section to see that same value? I tried the parameter name (didn’t work), I tried e (didn’t work), I tried Yn.e and it also didn’t work.

Thanks!
