AWAY %|[-one | -all] [<reason>]

   -one 
   -all

This command marks you as being "away". It is used to tell people that you currently aren't paying attention to your screen. You might use it if you are taking a nap, in the shower, getting some food, or otherwise just aren't there at the moment. When you're "away" you will see "(zZzZ)" in your statusbar.

Anyone who does a WHOIS on your nickname will see that you are away, as well as your away message. Anyone doing a WHO that returns information about you will also see that you're gone. 

By default, if someone sends you a MSG while you are away, your client will beep. You can turn this off by setting BEEP_WHEN_AWAY to OFF. 

If you send a MSG to someone who is away, you will automatically be notified of this. By default, you will only receive this notification once. If you wish to see it every time (to tell when a person is no longer marked away, for instance), change SHOW_AWAY_ONCE to OFF. 

You can remove your away status by using AWAY with no arguments.
