Binding action to a key for specific gamemode only

[Masster]

I want to set a key( for example B ) to perform specific task but since GM:KeyPressed() uses only IN_ keys I can't bind it to B. Is there a way to set a specific key to do a something for a specific gamemode only?

Is this for a game-mode you're working on, or one you're playing on?

You can use different config files, or use one of the various different key hooks. PlayerBindPress works if b is bound to something; the other key hooks don't always fire.
