First u need make config.cfg
Then, when u have done binds, like bind f6 "say killing is not allowed" u have to change ur binds like these:
bind f6 vstr 5656
Set 5656 "say KILLING IS NOT ALLOWED"
5566 can be anything u want like lol :
bind f6 vstr lol
Set lol "say KILLING IS NOT ALLOWED"
And for vsay that is same thing:
bind k vstr 1234
Set 1234 "vsay Hi ^6Hello Here is [n]"
They are just examples, u can have any kind of binds with capital letters.
