Sending messages and replying to messages are important ways to keep conversations active with your team. You can edit and delete messages after you’ve sent them.
Your System Admin may restrict Messaging actions, such as editing or deleting messages, by configuring Advanced Permissions, available in Mattermost Enterprise and Professional subscription plans.
Write a message by typing into the text input box, then press ENTER to send it. Use SHIFT+ENTER to create a new line without sending a message. To send messages by pressing CTRL+ENTER, go to Settings > Advanced > Send Messages on CTRL/CMD+ENTER > Edit.
Mattermost can automatically detect and display messages written using right-to-left scripts, such as Arabic, Hebrew, or Persian. Your System Admin must install the RTL Plugin to enable this functionality.
Select the More Actions link next to a message that you’ve sent.
Select Edit to edit your own messages. Message edits do not trigger new @mention notifications, desktop notifications, or notification sounds.
Select Delete to delete your own messages. Select Delete again to confirm.
Marking a message as unread bolds the channel in your sidebar, and adds the new messages line above the marked message. This can be a useful reminder to follow-up on the message later if you don’t have time to address it when the message was read.
Select the More Actions link next to a message, then select Mark as Unread.
