No, it really is a PythonCard question.

The thread you found is about console IO (or rather, standard input) for 
non-GUI applications. Detecting and handling input (such as "key" 
events) within wxPython (and PythonCard) is completely different.

I believe the KEY events aren't handled for a grid component, so you 
need to do it directly in wxPython. As a simple example, I added the 
following at the end of on_initialize in the simplegrid.py sample that 
came with PythonCard.

       
        ## try binding key_down
        mygrid.Bind(wx.EVT_KEY_DOWN, self.OnKeyDown)
       
    def OnKeyDown(self, evt):
        if evt.KeyCode() == wx.WXK_DELETE:
            print "Delete was pressed"
        evt.Skip()
        return

and it does properly detect "delete" when pressed after selecting a 
row/column  (and doesn't detect it when the delete is pressed within a 
cell editor).

You can find some more examples in the wxPython Demo samples if you need 
it ...
