How to speak in World of Warcraft, the first display is seeking a team?

First of all, the default channel of WOW team is /4. You need to press the I key to enter the team interface, for example, choose: Wail Cave, and then enter /4+ what you want to say in the dialog box. But generally speaking, after you form the first person, you will leave the team channel, so it is useless to you. You must press the I key again to enter the search window and select the corresponding FB.
