You can check out the configuration for company . You could for instance get rid of it auto popping and bind company-manual-begin to a key

how can I configure company?

I see the following in company.el

(defvar company-active-map
  (let ((keymap (make-sparse-keymap)))
    (define-key keymap "\e\e\e" 'company-abort)
    (define-key keymap "\C-g" 'company-abort)
    (define-key keymap (kbd "M-n") 'company--select-next-and-warn)
    (define-key keymap (kbd "M-p") 'company--select-previous-and-warn)
    (define-key keymap (kbd "C-n") 'company-select-next-or-abort)
    (define-key keymap (kbd "C-p") 'company-select-previous-or-abort)
    (define-key keymap (kbd "<down>") 'company-select-next-or-abort)
    (define-key keymap (kbd "<up>") 'company-select-previous-or-abort)
    (define-key keymap [remap scroll-up-command] 'company-next-page)
    (define-key keymap [remap scroll-down-command] 'company-previous-page)
    (define-key keymap [down-mouse-1] 'ignore)
    (define-key keymap [down-mouse-3] 'ignore)
    (define-key keymap [mouse-1] 'company-complete-mouse)
    (define-key keymap [mouse-3] 'company-select-mouse)
    (define-key keymap [up-mouse-1] 'ignore)
    (define-key keymap [up-mouse-3] 'ignore)
    (define-key keymap [return] 'company-complete-selection)
    (define-key keymap (kbd "RET") 'company-complete-selection)
    (define-key keymap [tab] 'company-complete-common)
    (define-key keymap (kbd "TAB") 'company-complete-common)
    (define-key keymap (kbd "<f1>") 'company-show-doc-buffer)
    (define-key keymap (kbd "C-h") 'company-show-doc-buffer)
    (define-key keymap "\C-w" 'company-show-location)
    (define-key keymap "\C-s" 'company-search-candidates)
    (define-key keymap "\C-\M-s" 'company-filter-candidates)
    (company-keymap--bind-quick-access keymap)
     keymap)
  "Keymap that is enabled during an active completion.")

it looks like C-n and C-p are explicitly hijacked.

I’m not really up on emacs scoping rules. Is there a way for me to remove something from this keymap after it has been loaded?

(define-key the-map (kbd "C-n") nil) yea like this

check the other custom variables in company. There is a few like 'auto-delay' etc.

good catch. seems like its not injecting the actual dep, just the middleware it expects to be present

Looks like there is an issue for that: https://github.com/clojure-emacs/sayid/issues/68

Yeah, that's the problem. Adding the dependency manually in your CIDER settings should fix this.

I'll fix this at some point, but I won't mind if someone beats me to it.
