Write messages

Format text, mention people, attach files, edit and delete messages, forward them, and schedule a message to send later.

Type in the message box at the bottom of a conversation and press Enter to send. Shift + Enter starts a new line.

Format text

Use the toolbar above the message box, or type the formatting yourself:

Format	Type	Shortcut
Bold	`text`	`Ctrl + B`
Italic	`_text_`	`Ctrl + I`
~~Strikethrough~~	`~~text~~`
Link	`[text](https://…)`
List	`- item` on its own line
Quote	`> text`
Code	`code`
Code block	``` on the lines before and after

Mention people

Type @ and the start of a name, then pick from the list with the arrow keys and Enter or Tab.

Mention	Who it notifies
`@name`	That person.
`@channel`	Everyone in the channel.
`@here`	Everyone in the channel who is active in Relay right now.
`@role`	Everyone in that role (from Team & Permissions) who is in the channel.
`#channel`	Nobody — it links to a channel.

A mention of you is highlighted in the message.

Typing @Pr in the message box shows matching people

Add an emoji

Click the smiley in the message box, or type an emoji from your keyboard.

Attach files

Click the paperclip, drag files onto the conversation, or paste an image. You can attach up to 10 files to one message, and each file can be as large as your workspace's upload limit (50 MB unless your administrator changed it). Images and PDFs open in the browser; other files download. Every file shared in a channel is listed in its Files tab.

Edit or delete a message

Hover a message and click ⋯, or right-click it.

Edit message changes your own message. Press ↑ in an empty message box to edit your last message. Enter saves, Esc cancels. The message shows (edited).
Delete message removes it. If it already has thread replies, the replies stay and the message reads "deleted". You can delete your own messages; the channel's admins and people with Can moderate can delete anyone's.
