How to you make your player scream in Left 4 Dead and Left 4 Dead 2

left-4-deadleft-4-dead-2

I remember when I played Left 4 Dead, a couple of months ago, that some players were able to let their controlled character do a scaring long scream.

How did they do? Is it possible to do this also in Left 4 Dead 2?

Valve removed the vocalization commands to stop people spamming in multiplayer games, all that is left are the speech wheel that come up when you press z or x (using default controls).

Edit: This is the very hacky way of doing it through the radial commands which may or may not work.
