"ENTER" key in text editors

In the current editor, the "ENTER" key is used for submitting, while the line break behavior is achieved with SHIFT+ENTER, which is similar to many applications.
Pressing "ENTER" alone triggers the submit action without any confirmation, and in practice, I have made several unintentional submission errors as a result.

Believe me, whether on a desktop or a mobile device, it's very easy to accidentally press "ENTER."
While this may not be a bug and is more a matter of different usage patterns, I still recommend that in the editor, "ENTER" should solely be responsible for line breaks, and the submit action should require an actual button click.
