Further improvement is the following configuration:

```emacs-lisp
(use-package company
   :bind
   (:map company-active-map
    ("<tab>" . company-search-candidates)
    ("<backtab>" . company-search-abort)
    ("SPC" . company-complete-selection)
    ("<return>" . company-abort)

    :map company-search-map
    ("<tab>" . company-search-candidates)
    ("<backtab>" . company-search-abort)
    ("SPC" . company-complete-selection)
    ("<return>" . company-abort))

  :config
  (setq company-tooltip-limit 15
      company-quick-access-keys '("1" "2" "3" "4" "5" "6" "7" "8" "9"
"0" "=" "\;" "\`" "\," "\/"))

   (defun hz-company-number ()
    "Convert the company-quick-access-keys to the candidates' row
NUMBER visible on the tooltip,
     and then feed it to `company-complete-number' to quickly select
and insert company candidates.
     If the currently entered character is belongs to
company-quick-access-keys and a part of the candidate simultaneously,
     append it to the currently entered string to construct new company-prefix."
    (interactive)
    (let* ((k (this-command-keys))
           (re (concat "^" company-prefix k)))
      (if (cl-find-if (lambda (s) (string-match re s))
                      company-candidates)

      (self-insert-command 1)
    (company-complete-number
     (cond
      ((equal k "1") 1)
      ((equal k "2") 2)
      ((equal k "3") 3)
      ((equal k "4") 4)
      ((equal k "5") 5)
      ((equal k "6") 6)
      ((equal k "7") 7)
      ((equal k "8") 8)
      ((equal k "9") 9)
      ((equal k "0") 10)
      ((equal k "=") 11)
      ((equal k "\;") 12)
      ((equal k "\`") 13)
      ((equal k "\,") 14)
      ((equal k "\/") 15))
     ))))

  (let ((map company-active-map))
    (mapc (lambda (x) (define-key map (format "%s" x) 'hz-company-number))
      '(1 2 3 4 5 6 7 8 9 0 = \; \` \, \/))))
```
