I give GiantOrange from "gamefaqs" mad props for finding this!

Locate autoexec.cfg in main folder

add this:

set duck "+movedown; set crouchToggle vstr stand; echo ^3Crouching...^7"
set stand "-movedown; set crouchToggle vstr duck; echo ^2Standing...^7"
set crouchToggle "vstr duck"
bind c "vstr crouchToggle"

Change C to whatever you want.
