How do I change yawspeed?

I just decided to start surfing on CS:GO after surfing on other games previously, but I can't figure out how to change the yawspeed. cl_yawspeed isn't a real command, and when I change m_yaw like I've seen on other forums, I don't see any significant change. Is there another command instead?

you cant change yawspeed but if you bind walk to something and turnbind at the same time is slows it down a bit

so something like "bind mouse1 walk, +left"?

idk but i just use like mouse4 for walk

I use: bind c +left; bind v +right
