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?
Oh, the shortcut is now shift+tab.
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
