Feature: Enter to submit (important usability feature)

I would like to submit content on press enter. Currently, I see no way of doing that. I tried to implement my solution but sometimes it creates an empty bloc on press enter. Is there a way to send a message on **Press Enter**?

```
/**
* submit on enter
* @param e
*/
async submitOnEnter(e: Event) {
const event = e as KeyboardEvent;
const condition1 = event.key === 'Enter';
const condition2 = !event.shiftKey;

// stop on empty text
if (condition1 && !this.contentInput?.str) {
e.preventDefault();
e.stopPropagation();
return false;
}

if (!this.isSubmitOnEnter) return;
if (!this.contentInput?.str) return;
if (!(condition1 && condition2)) return;

// submit
this.contentSubmit();

// stop new line
e.preventDefault();
e.stopPropagation();
return false;
},
```
