Completion settings about Ruby on IntelliJ IDEA

Hi,

I want to know about completion settings about Ruby on IntelliJ IDEA.

Can I set "chose with only enter key" for Ruby, cause I'm used to using Golang or PHP with enter key choice in completion?

In case Ruby, below,

```

sample = "foo"

bar = samp

```

After typing this, I need to type "down key" and choose variable then type "return key" from completion list, but like Golang, no need to type "down key", but already selected variable and easily type "return key".

How should I do for it like Golang to make my ruby coding easy?
