I think it actually is documented - maybe you weren't aware that you
can use a cs-list as index, but this more or less follows from the
docs, I think. Another trick is maybe that you can use the ':' string
instead of : - I think that's documented too, though I'm not sure. The
rest is just thinking...
In any case, feel free to improve the docs, clarify anything, provide
any examples you find useful. I think there's nobody there thinking
that Octave's documentation is too detailed.
