Not always, sometimes, people hide the console from their server.
It would be nice to have a key absolutely un-used (Like numpad "5").
And when you need to, you press it and you're disconnected from the server.
Without obviously using the console.
Do you think it's possible people?
Rcon and Console are two things entirely. Rcon is used to control a server when you're host or have the password. A console allows you to use Dvars and commands.
Key binding is possible. I mean how else would they bind usual keys?
