How do I find what might be mapped to some key combo? and how do I see if it’s mapped into certain modes?

Hm, SPC h d b, but unfortunately it’s a lot to sift through

(Spacemacs) Error in dotspacemacs/user-config: Symbol's value as variable is void: helm-map

(setq-default hybrid-style-enable-hjkl-bindings t)
  (define-key helm-map (kbd "C-n") 'helm-next-line)
  (define-key helm-map (kbd "C-p") 'helm-previous-line)

  ; C-n and C-p to quickly move between open buffers
  (unbind-key (kbd "C-n") evil-mc-key-map)
  (global-set-key (kbd "C-n") 'next-buffer)
  (unbind-key (kbd "C-p") evil-mc-key-map)
  (global-set-key (kbd "C-p") 'previous-buffer)

I get an error for the help part I don’t understand, and after unbinding the evil-mc binding, there’s another one under it. How do I unbind everything from that key? or do I just have to keep chasing it down. ideally I’d like to overwrite that binding on everythign and then reapply the bindings I want
