# [IPython-dev] Tab behavior in a function call in notebooks on 2.0

Hi,

I used to be able to hit <tab> while writing a function in the
notebook and get the documentation in a pop-up. E.g.,

np.array(<TAB>

Somewhere during 2.0.0 development this behavior seems to have stopped
working. It worked three weeks ago at 487ee99. I now get a list of
pretty much everything an empty word could tab-complete to when I try
the above. I found the old behavior to be very helpful and more
natural than the ? behavior of a new pane in the browser.

Is there a way to re-enable this?

Thanks,

Skipper
