Meaning of ーたりしない


I've come across the following sentence while watching a show :

> こんな所で立ち止まったりしない

...which, according to the subtitles, translates as :

> [She] won't stop after coming all this way.

I had a rough idea of what this meant without the subtitles, but I'm unclear
on how it works grammatically : why is the ーたり suffix used here? Why not
simply use something like 立ち止まらない ?




In addition to the basic usage of giving examples, you can use たり with some
"unlikely" thing and emphasize how unexpected or extraordinary it is. It can
be translated in many ways.

>   * 彼、本気だっ **たり** して! _Maybe_ he is serious!  
>  ([～たりして](https://japanese.stackexchange.com/q/5705/5010) is a set phrase)
>   * 地図を持ってい **たり** しますか? _By any chance_ , do you have a map?
>   * 私は彼の友達だっ **たり** する。 I _happen to_ be his friend.
>   * 負け **たり** するなよ。 Don't you _ever_ lose!  
>  (as compared to 負けるなよ, this sounds less serious, or implies the speaker
> believes the listener is unlikely to lose)
>

こんな所で立ち止まったりしない is close to the fourth one above. This たり emphasizes how
unexpected 立ち止まる is in the context.
