By default to move up (ctrl-p) and to move down (ctrl-n) key bindings are used.
When I am using auto-complete mode, a box with suggested words is pop up. On there when I press ctrl-p or ctrl-n instead of moving within the box, it closes from it. I can move around only by using tab or alt-p or alt-n.
[Q] Inside the box for suggessted word to auto-complete, is there any way to move around by ctrl-p and ctrl-n?
You can configure that behaviour via customize.
Just do M-x customize-option <return> ac-use-menu-map <return>, then set this option to on (non-nil) and save it for future use.
Thats it.
How did I get this information? I looked at the source code. But it was also possible to find this from M-x customize-group <return> auto-complete <return>.
Nevertheless, I would recommend, switching to another completion framework (like company) because auto-complete seems abandoned. With last commit in Jan 2017.
Edit: To enable this behaviour with company, simply bind the keys and corresponding functions in companys keymap:
(with-eval-after-load "company"
(define-key company-active-map (kbd "C-p") #'company-select-previous-or-abort)
(define-key company-active-map (kbd "C-n") #'company-select-next-or-abort))
company but same issue exist on it as well. Is there any way to handle it on company too?
C-h for delete character as well on company? instead of deleting it says No documentation available.
<up>and<down>? Often those are used (also or instead) in places where you might expectC-pandC-n, respectively, to be used .ctrl-pandctrl-nall the time @DrewC-pandC-nto the commands you want in the relevant keymap (maybe it'sauto-complete-mode-map?).
