I have lost my emacs config and I try to reconfigure my .init.el on my work station.
I have install helm and defined :
(global-set-key (kbd "C-x C-f") 'helm-find-files)
I have the good windows, but in my last configuration i was able to navigate through my project with the keyboard arrow.
C-x C-f --> /home/foo/bar/
left arrow --> /home/foo/
right arrow --> /home/foo/bar/
In my emacs, actually, this behaviour is not reproducted. What should I do to have it ?
