Default reprogramming in tkinter

Question

I am adding a binding to my root window (an instance Tk()that contains a text widget):

root.bind("Control-o", setconnpanelopen)

The problem is that, control-oby default, it binds to "insert newline", so my procedure fires, but it also inserts a new line! This happens even if I put it return 'break'in the end - so it works earlier, so it seems.

1) how can I reassign this behavior?

2) I have not found a list of standard keybindingstext widgets anywhere - are they available somewhere?

        Text.__init__(self, master, **kw)
        self.bind('<Control-O>', setconnpanelopen)

, setconnpanelopen "break".
