There's no PythonCard method to do this directly. You can use the 
wxPython methods (I stole / adopted this code from the 
components/multicolumn.py). 

I took the multicolumnexample in the samples directory, added a button 
called "which" and added the code below.
It prints out the list of selected item row numbers - and then makes the 
row following the first selected one be (also) selected.

You'd need to (assuming you want to) first de-select the current 
selection, then select 667 as you want - something like
    for i in items:
        self.components.theList.SetSelection(i, 0)    # second param 0 
to deselect
  self.components.theList.SetSelection(667)

What did the MessageWatcher say the event was ?

It's itemActivated  :-)

Yes.
