I presume you made that modification because Helix warned him about "/qui gon trolls"?
@Gråtrunka To clarify: "/qui" autocompletes to "/quit" no matter what you type afterwards, closing the game. A similarly popular troll suggestion is "/disco", which autocompletes to "/disconnect". (I'm not sure if this is possible in all clients, but it obviously works in at least one of them or nobody would be trying to trick you.)
When in doubt about a 'command' like that, try pressing Tab instead of Enter to see what the game thinks you're going for.
