Thank you for your correction. I've tried the following but still
can't get the same effect as using two different keys:

(use-package company
 :bind
 (:map company-active-map
    ;; ("<tab>" . company-search-candidates)
    ;; ("<f1>" . company-search-abort)

    ("<tab>" . (lambda ()
             (interactive)
             (if (company--active-p) #'company-search-abort
               #'company-search-candidates)))

    :map company-search-map
    ;; ("<tab>" . company-search-candidates)
    ;; ("<f1>" . company-search-abort)

    ("<tab>" . (lambda ()
             (interactive)
             (if (company-search-mode) #'company-search-abort
               #'company-search-candidates)))))

Dmitry Gutov told me the following fact [1]:

company-search-candidates is incremental (like isearch), so it's not
going to exit when you call it a second time.

You can write your own command easily enough, though.


But I still can’t find an effective solution that uses only one key to
get exactly the same behavior given by two separate keys.
