[IPython-dev] ipython notebook "current cell changed signal"

OK. I have finally figured this out by myself :-)

'selected_cell_type_changed.Notebook' is
actually what I was looking for.

I was misled by the naming. My first thought was
that the 'selected_cell_type_changed.Notebook' signal
was /only/ triggered when the selected "cell type" was
changed, actually it is triggered either when the
"selected cell" or the "selected cell type" are changed...

Best regards,
