But I don't want it to just go to the top-level, I want it to respect
the current
nesting level.  If I insert yet another level in the example, and
point is within
the second level of nesting, I want it to move to the beginning and end of that
nested function (i.e., "secondLevel" in the sample below when point is on the
call to innerFunction).  As mentioned in my original email, python-mode does
respect the nesting level correctly, but python-ts-mode, and other "ts" modes
that support nesting, don't respect it.

def outerFunction(text):
    text = text

    def secondLevel(text):
        print(text)

        def innerFunction(text):
            print(text)

        innerFunction()

        def innerFunction2(text):
            print(text)

        innerFunction2()

    secondLevel()
