This page explains the ins and outs of messaging in Rocket.Chat.
To compose a message in Rocket.Chat, go to the channel or user you want to send a message to. Type the message in the message box and press Enter or the Send Button.
If you want to add new lines of text, press Shift + Enter to add a new line.
While writing or editing messages, you can move the cursor using the arrow keys. Where the cursor moves depends on the wrapping of the text.
Hold Alt or Command while pressing the right or left arrow keys to move the cursor to the beginning or end of the message.
To get the attention of a specific team member in a channel, type @ followed by their username, for example, @username. The mentioned user sees a red badge on the channel or is notified via email or their mobile device if they're not online.
You can also notify everyone in a channel by typing @all. Although notifying everyone in the channel is useful for announcements, not every message requires this. We recommend using @all sparingly.
You can send a variety of attachments with your messages, like files, audio, links, videos, and many more.
To access the attachment menu you can, click on the plus (+) icon on the message input.
You can select files using three methods:
By choosing the Select Files from Computer option from the attachment menu
By dragging and dropping the file on Rocket.Chat
By pasting an image from the clipboard
After selecting the file, add a name and a description of the file and press Send.
Remember that the server administrator can block certain file types from being uploaded.

Files can be uploaded from Google Drive to a room by selecting the Select Files from Google Drive option on the attachment menu. This opens a Google Drive file picker GUI with search and view modes. Select the required file, enter a title and description, and then click Upload.
Files are upload in the same format as they are stored in Google Drive with exception of Google Docs, Google Slides, and Google Sheets which are converted to pdf upon upload.
Files uploaded as a message attached to a room can be uploaded to Google Drive. Click Save to Google Drive above the file attachment. The file saves to Google Drive in its original format.
Create Google docs, slides, and sheets by clicking to corresponding file type in the attachments menu. The file saves to that user's Google Drive account and posts on the message or channel from which creation occurs. The sharing setting for the file shall remain default. It can be changed by the file owner via the link to collaborate with other users.
URLs to other sites automatically generate a preview of that site's content. Copy and paste the link into the message box to create the preview.
To share your location, click Share My Location. A message with the link to your location on Google Maps is generated.
To insert an emoji, click the smiley face icon in the message box. Browse through emoji using the icon categories or through the search box.
Rocket.Chat changes common emoticons, or symbols used to represent emoji, to the equivalent emoji. For example, :) converts to the :smiley: emoji.
When graphical emojis are disabled, emoji keywords and shortcuts display as regular text.
Use the following symbols to format text as desired:
Bold: *Lorem ipsum dolor*
Italic: _Lorem ipsum dolor_
Strike: ~Lorem ipsum dolor~
Inline code: `Lorem ipsum dolor`
