How do i send a multi line message?

[drewverlee]

By multiline message, I mean something like this:

look at this code:
(wow)

When i get to "look at this code:" and i want to create a new line, but not send the message, I'm at a loss as to what to press. I can also copy and paste a multiline message into the Slack buffer.

Enter sends the message. What just creates a new line?

@drewverlee C-q C-j.

That is, quoted-insert (C-q) followed by a newline (C-j).

This works across Emacs! You can use it almost everywhere you want to insert a newline without invoking Enter. For example, you can use this to insert newlines into the minibuffer.
