These are typed directly into the text area - simple as that?
/nick <new nickname>
Example: /nick BeansAndCheese would change your nickname to BeansAndCheese
/query <user> <message>
Example: /query moo42 so you're running ChromeOS on a mac too? would send user moo42 a private message saying so you're running ChromeOS on a mac too?
Note: Depending on your IRC client, a new conversation may or may not pop-up immediately. Be patient, as soon as they respond you will definitely get a new window.
