As in fact on the @mamady answer, you can get the name of the function that get fired on mouseDown using getEventListener($0).mousedown[0].listener.name with Chrome dev tools.

As you see, probably the function name does not appears beacause it does not have a named function, so the function is annonymous, but you can see the location of the function:

If it’s not, you can see the name of the function:

If the main problem is another (you have to get the name of the function to do something, what something?), please comment here.
