chat options

[JHeroGHJP]

hello,i'm looking for a addon that shows like a menu the options to change which chat we are talking...i'll do some ascii now:

(G)|------------------------| |
(P)| |
(5)| |
(R)|_____________________|

in my vision of this ascii G means guild chat,P means party,5 means the 5th channel,and r stands for RAID
is there some addon for this?
