does Binding Keys to cheats disrupt achievements?

[Blue]

Well Neighbourhood watch I got when I was far less competent in Source Engine games than I am today.

But regardless, I still got "Get Some Grub" and "Little Rocket Man" without cheating.

 

In Episode 1 I also got "One Free Bullet" first try without dying.

(Protip: Unbind all weapon switching keys and controls except to Weapon categories 1 and 5.)
