How can I bind vertico-insert to toggle in the list?

Question

I am using find-file with vertico. After running find-file and typing filename and when I press <TAB> it selects the current line.

TAB runs the command vertico-insert (found in vertico-map), which is an
interactive byte-compiled Lisp function in ‘vertico.el’.
It is bound to TAB.
(vertico-insert)

Instead, is it possible to bing <TAB> as to toggle inside the list of find filenames?

maybe (define-key vertico-map (kbd "<tab>") 'vertico-next) — roomworoof, Apr 28 '23 at 12:14
@roomworoof it did not helped , like it still remains as (vertico-insert):-( — alper, Apr 28 '23 at 12:58
As for this setting, I tried it in my environment and it worked, but I also have had the same experience as you, I could not overwrite keymap in another case. I wonder what the cause is. — roomworoof, Apr 28 '23 at 13:21

Try TAB instead of <tab> and it will work.

(define-key vertico-map (kbd "TAB") 'vertico-next)

Since TAB (not <tab>) is used in the source (defvar-keymap vertico-map ...), this should overwrite it correctly. I just learned for the first time that TAB and <tab> are different things...

<tab> = Tab (GUI only)
TAB = C-i = Tab (Terminal, or GUI if <tab> is not set)

They say it's for historical reasons, see StreakyCobra's comment (referred by another questioner @Håkon Hægland on this site: What is the difference between TAB and <tab>?)

It works! Not sure but can it toggle cycle like back to top if the selected line is at bottom? – alper Apr 29 '23 at 10:29
(setq vertico-cycle t)? – roomworoof Apr 29 '23 at 10:32

If you don't want to go back to the prompt line by setting vertico-cycle, define another function like this:

(defun my-vertico-next (&optional n)
  "Circulate without returning to the prompt line"
  (interactive "p")
  (let ((index (+ vertico--index (or n 1))))
    (vertico--goto
     (if (= vertico--total 0) -1 (mod index vertico--total)))))
(define-key vertico-map (kbd "TAB") 'my-vertico-next)
