I’m using the Quill 2.0.2 JavaScript library to edit content with different heading styles (h1 to h4). Currently, when I’m typing with the h2 style and press ENTER, Quill switches to the “Normal” style (<p>). Instead, I want it to switch to the h3 style.

I’ve tried customizing the keyboard bindings, but with no success, and doesn’t seems it is the right approach. How can I make Quill keep the header format and switch from h2 to h3 when ENTER is pressed?
