in CPMA 1.48, I see that "add: cq3/dev crouchsliding",

then I run Quake 3 into CPMA console and type "server_gameplay CQ3", after this I cant do aircontrol anymore so I think Im already change it,

and then, Im into a map and type"add: cq3/dev crouchsliding", but is nothing happen,

and I try
"cq3/dev crouchsliding",
"/dev crouchsliding",
but still cant crouch slide,

so please whats the right console commend?

how can I do?
