You can send long, multi-line messages in the chat in a few ways:

• Paste a multi-line message directly into the chat.
• Enter { alone on the first line to start a multiline message and } alone on the last line to end it.
• Use Meta-ENTER to start a new line without sending the message (Esc+ENTER in some environments).
• Use /paste to paste text from the clipboard into the chat.
