Hi, I'm using vertico as a completion framework and it's working
great. But I want to change its default behaviour when opening a new
file. Rather than opening file with new buffer, I want to open in
split window vertically or horizontally with a keybind. Thank you

Use C-x 4 f (find-file-other-window). There's also `display-buffer-
alist` which controls how and when Emacs splits the window.

I'm not sure but my advice is that always read the doc [vertico
wiki](https://github.com/minad/vertico/wiki)

And if you want lightweights emacs configuration checkout
[funmacs](https://github.com/xmawja/funmacs)

May find it useful.

Thank you, I've read wiki section ready but it doesn't feature my use
case. Come from vim, I'm used to use C-v to open vertical buffer from
completion buffer. But I couldn't emulate this behaviour with emacs. I
bound `C-v` to `vertico-map`, but it says *attempt to split minibuffer
window*

*Update:* with `embark`, I could bind `C-v` to `split-window-
vertically` in `embark-file-map` as a workaround. However, this is 2
steps binding, first I have to activate `embark-act` then `C-v`, this
is inconvenient.

You said you *have* to use two keystrokes, one for `embark-act` and
then one for `split-window-vertically`, but this is Emacs! Nobody can
force you to press two keystrokes against your will:

    (define-key vertico-map (kbd "C-v") (kbd "C-. C-v"))

(Replace C-. with whatever you use for `embark-act`.)

That's probably the easiest way, but you could also define a command
following any of the methods [I described here](https://www.reddit.com
