## Settings
To use tab instead of enter to complete your selection, `dotspacemacs/init` set `company-mode/use-tab-instead-of-enter-to-complete` to true, for example:
```
(defun dotspacemacs/init ()
"User initialization for Spacemacs. This function is called at the very
startup."
(setq company-mode/use-tab-instead-of-enter-to-complete t)
)
```
