Hi this is a little instruction:
if u see that picture that i attached:first use crash tweak,then press K then J
there is a little comfortable function, u can mute or unmute with 8 button and u can easily add some power to the sound or take back it with 6-7 button
my tweaks on the arrows
bigger killfed 8-9 line if I remember well
classes scope=z  specops=u assault=i
weapnext=x
toggle fps=mouse4
thats all i want,i hope u will like this config:)
