Running control help

Tl;dr - I’m new to PC gaming and I wanna look behind me when running without changing direction, dunno how to do it.

Hi guys, is there any way to change the direction of the camera without changing the direction in which I’m running or walking, like there is on horseback? So, for instance, I’m being chased and I want to look behind me to see where they are, but when I look at them I automatically change the direction I’m running in so I’m going towards them. I just want to look behind me and keep running forward.

I know I could just turn behind and quickly press ‘s’ so I start walking backwards, but if I’m trying to do that quickly and often I just end up fumbling and it’s annoying.
