IPython Notebook Tab-Complete — Show Docstring

问题:

I just upgraded to IPython 2.0.0 and the behavior of tab-complete seems to have changed for the worse. (Using pyreadline 2.0, which according to this question might matter).

Formerly, if I hit TAB after function_name(, IPython would show the docstring for that function.

Now, I just see a dropdown list of what I guess is everything in the namespace, including:

• Error types
• names of other notebooks in the directory
• IPython magic functions
• Other functions I've defined
• etc.

The old behavior was super helpful -- how can I restore it (short of reverting to an earlier IPython version)?

Apparently it's now Shift-Tab. Thanks @Thomas K.
