deaf quiet
The DEAF toggle turns off incoming tells.
This is helpful if you are being bombarded by messages from other players.
You can still use reply (see 'help reply') to reply to people who were telling
you before you went deaf, although you cannot reply to a deaf person. (it's
mostly useful for sending a quick "I'm being spammed so I went deaf" message to
a person).
The QUIET toggle turns off all channels (tells, yells, etc.) except for emotes
and says.
