To talk to others in There, type your message on the keyboard. Your words will appear in a chat balloon above your head, visible to those around you. When you have finished a sentence, press Enter.
If you do not press Enter when you are finished speaking, the last thing you say will remain in a chat balloon over your head, even when walking or running. This can be useful if you'd like to leave a message. For example, if you must step away from your keyboard you could type, "I'll be right back."
