How do i enter cheat codes for- Crysis Warhead on the PC?

Hey! Not for anything but I'm new in the Crysis warhead community

And I'm wondering how to imput cheats;

(for the more difficult scenarios)and levels; and then go

Back and game without the codes on normal mode.

I know about the (tilde) key- and then the subsequent code

But how do I enter the shortcut for "devmode"?

Thanks guys, Ron.How do i enter cheat codes for- Crysis Warhead on the PC?
