Messaging Basics

---

Write messages using the text input box at the bottom of Mattermost. Press ENTER to send a message. Use SHIFT+ENTER to create a new line without sending a message.

Reply to messages by clicking the reply arrow next to the message text.

Notify teammates when they are needed by typing @username.

Format your messages using Markdown that supports text styling, headings, links, emoticons, code blocks, block quotes, tables, lists and in-line images.

Quickly add emoji by typing ”:”, which will open an emoji autocomplete. If the existing emoji don’t cover what you want to express, you can also create your own Custom Emoji.

Attach files by dragging and dropping into Mattermost or clicking the attachment icon in the text input box.

Flag messages for follow up by clicking the flag icon next to the message timestamp.
