Hello.

Yes, that is indeed the way to set the editor. I have done that,

But what I mean with line editor is that one can use vi commands on the
'command line'.

With ksh you invoke it with 'ksh -o vi'
then if you want to eg complete a word, you press Esc and \

Or if you want to go back in command history you use the vi arrow keys,
for instance Esc+k


This is what I would like to do in iPython.


Kind regards,
