function name + tab does not return docstring in IPython

Question

In IPython, I am used to write

function(

and then strike a tab, and get the contents of the docstring and a list of the named arguments. However, this stopped working since I installed IPython 2.0. Is there an explanation or a know fix?

Answer 1

Oh, the shortcut is now shift+tab.

Answer 2

Shift-tab only works when you place the edit cursor inside or after the object. Not when it's at the start of the object. This gotcha is not documented anywhere...!

I filed jupyter issue Shift-Tab completion doesn't work when edit cursor is at the start of the object #1902
