When chatting with a Jabber contact using iChat, you can use IRC-like /me syntax to perform actions. For instance, typing...
/me wants a Napa-based PowerBook with a
dual-core Pentium D, a 533MHz FSB, DDR2 RAM and SATA II.
... will produce this output:
Stephanos Piperoglou wants a Napa-based PowerBook with a dual-core Pentium D, a 533MHz FSB, DDR2 RAM and SATA II.
Well, assuming your name is also Stephanos Piperoglou, that is. This does not work with AIM chats.
