Write a multi-line message without sending early
Write a multi-line message without sending early in Cortex Chat: practical steps, setting explanations, result checks and troubleshooting.
Enter normally submits the composer. Shift+Enter creates a line break, which is useful for a task containing a short list or structured context. Mention selection and input-method composition can change how Enter is handled.

Before you start
The active composer determines where text, mentions and attachments will be sent. A private assistant panel can sit beside a shared conversation, so check the heading as well as the visible text. Inspect the file or recording before sending it; a local preview is not a completed upload. Chat validates a single attachment and rejects empty, oversized or unsupported files. Receipt state describes the message transport, not the success of a task requested inside it. If the result is uncertain, inspect the existing conversation and any external destination before retrying. This is especially important when a message asks the assistant to send, book or create something.
Step-by-step
- Click the composer and type the first line.
- Use Shift+Enter for each deliberate line break.
- Review the complete text and submit only when the recipient and instructions are ready.
What the settings mean
| Control or state | Meaning |
|---|---|
| Composer | The current destination for text and pending media. |
| Preview | Content selected locally and still awaiting the send action. |
| Receipt | Sending, failed, sent, delivered or read information. |
| Task result | The separate artifact or external action requested in the message. |
Check the result
The assistant receives one complete structured request rather than several accidental partial messages.
If it does not work
If a mention menu is open, Enter can select its highlighted candidate. Close it or complete the mention before expecting Enter to send the full message.
Continue with the right context
