Hi Chris,

Not sure if this reproduces what you want or not. I use PyCharm (free for free stuff, and very affordable/worthwhile otherwise) on Linux (as well as OSX/Windows). I made a new project, added two files:

provider.py:

class Provider(object):
    def stop(self):
        pass

usage.py:

class Conglomerate(object):
    def doSomething(self):
        self.provision.stop()

I then highlight 'stop', hit Ctrl-B (menu option go to>>declarations) and it brings up all the stop() definitions it could find, the Provider one on the top, click it and I jump there. Ctrl-Alt-B (menu option for goto>>implementation(s)) does nothing… UNLESS… I add this method to Conglomerate:

    def __init__(self):
        super.__init__()
        self.provision = Provider()

Then go to implementations takes me right there to the other file.
