# -Q2.D.3- select items in more than one Tk listbox at a time?

    From: -II-  Tk Questions and Answers - How can I:

    A2.D.3. The default for Tk's listbox widget exports its selection as the
    X selection.  There can only be one of these at a time.

    To turn off this behavior in Tk, use the -exportselection false when
    you create the listbox.  Or, use the

    option add *Listbox.exportselection false

    command in the beginning of your script.
