Writing messages

Type in the box at the bottom of a channel or conversation and press Enter to send. A message can be up to 8,000 characters. Use Shift+Enter for a new line. The formatting bar above the box has buttons for Bold (Ctrl+B), Italic (Ctrl+I), Strikethrough, Code, Code block, Quote, Bulleted list and Numbered list.

Formatting

CM Chat uses a small, simple set of formatting marks.

Messages are shown as safe text. You cannot add HTML, scripts or pictures through formatting. To share a picture, attach it; see Files and images.

Mentions

Type @ and the first letters of a name. Pick the person from the list. They get a mention marker (see Unread messages and mentions).

Two special mentions:

• @channel alerts everyone in the channel.
• @here is meant for people who are around right now.

Use these sparingly. They draw the attention of the whole channel.

Emoji

1. Click the Emoji button in the message box. You can also type a colon and a name, such as :smile:.
2. Search or browse, then click an emoji.

You can also type or paste emoji directly.

Edit a message

You can edit only your own messages.

1. Point at your message.
2. Click More actions (three dots).
3. Click Edit message. Or press the Up arrow in an empty message box to edit your last message.
4. Change the text, then press Enter or click Save. Press Esc or click Cancel to stop. The message shows "(edited)".

Delete a message

1. Point at your message and click More actions.
2. Click Delete message.
3. In Delete this message?, click Delete.

The text and any attached files are removed for everyone, and a "This message was deleted." note stays in its place. A workspace admin can also delete a message; this is recorded in the audit log.
