The stream can be canceled at any point with <kbd>escape</kbd>. This is useful if you realize early on that the response is not what you were looking for.

If you want to start a new conversation at any time, you can hit <kbd>cmd-n|ctrl-n</kbd> or use the `New Chat` menu option in the hamburger menu at the top left of the panel.

Simple back-and-forth conversations work well with the text threads. However, there may come a time when you want to modify the previous text in the conversation and steer it in a different direction.

## Editing a Text Thread {#edit-text-thread}

Text threads give you the flexibility to have control over the context.
You can freely edit any previous text, including the responses from the LLM.
If you want to remove a message block entirely, simply place your cursor at the beginning of the block and use the `delete` key.
A typical workflow might involve making edits and adjustments throughout the context to refine your inquiry or provide additional information. Here's an example:

1. Write text in a `You` block.
2. Submit the message with {#kb assistant::Assist}.
3. Receive an `Assistant` response that doesn't meet your expectations.
4. Cancel the response with <kbd>escape</kbd>.
5. Erase the content of the `Assistant` message block and remove the block entirely.
6. Add additional context to your original message.
7. Submit the message with {#kb assistant::Assist}.

Being able to edit previous messages gives you control over how tokens are used. You don't need to start up a new chats to correct a mistake or to add additional information, and you don't have to waste tokens by submitting follow-up corrections.

> **Note**: The act of editing past messages is often referred to as "Rewriting History" in the context of the language models.

Some additional points to keep in mind:

- You can cycle the role of a message block by clicking on the role, which is useful when you receive a response in an `Assistant` block that you want to edit and send back up as a `You` block.
