Trying to emulate on company Vim behaviour

Hi, I'm making the switch from **Neovim** to **Emacs** for **Clojure**
development.

For the completion I'm used to `<Tab>` and `<S-Tab>` for cycling
through suggestions, and the suggestions would be automatically placed
in the buffer when selected so that `<Enter>` would only behave as a
newline.

This is what I got for now:

```elisp
(use-package company
  :init (add-hook 'after-init-hook 'global-company-mode)
  :config (global-company-mode t)
          (setq company-minimum-prefix-length 1)
          (setq company-idle-delay 0.0)
  :bind
  (:map company-active-map
        ("TAB" . company-select-next)
        ("<backtab>" . company-select-previous)
        ("RET" . nil)))
```

Issues:

1. Now I don't have a way to autocomplete since when I select
suggestions they don't get placed in the buffer
2. Placing `S-TAB` instead of `<backtab>` in the `:bind` section
doesn't work
3. If I tap `<S-Tab>`, then pressing `<Enter>` becomes unresponsive

Thanks! Any help is appreciated. :D
(Also if you see some bad practice tell me please)

EDIT: did I do something wrong? I see a 50% of downvoting rate

> :init (add-hook 'after-init-hook 'global-company-mode)

there's `:hook` keyword


> setq

some people prefer using `:custom` keyword instead

also, to be sure the snippet works everywhere it's better to set
`:ensure t`

Thanks! I also have this line on `init.el` that I think handles that

```elisp
(setq use-package-always-ensure 't)
```
Anyway nice tips. Thanks for helping :)

Take a look a the customisation variables `company-insertion-on-
trigger` and `company-insertion-triggers`

[https://company-mode.github.io/manual/Customization.html#Customizatio
n](https://company-
mode.github.io/manual/Customization.html#Customization)

I didn't try it, but it seems helpful.
