You can simultaneously chat with multiple buddies by double-clicking another buddy while you are already chatting with a buddy. The conversation with the second buddy opens in a new window and the new buddy tab is added to the panel. When the number of buddy tabs exceeds the space limit of the panel, an arrow appears. Click the arrow to view the remaining list of buddy tabs as a list. When you choose a buddy from this list, the selected buddy moves to the Instant Messaging panel and the buddy next to the arrow gets added to the list. When a new message is received from a buddy who is in the list, the arrow is highlighted.
