Chapter jump

[Max_Fall]

I was just wondering how do you skip chapters in HL2.I know its a cheat but i dont know how it goes,i just wanted to play some of the last chapters,and i cant go through the entire game again (ive done it like 5 times,and ervenholm freaks me out)
Help will be very much apreciated by fellow gamer

Ervenholm?
I believe it does freak you out. You can't even remember the name...
