codemirror-promql VS dev

I'm using CodeMirror 6 for promlens.com and together with the lezer parser generator, it was great for developing syntax highlighting, contextual autocompletion, and inline linting for PromQL (that part is OSS actually, in https://github.com/prometheus-community/codemirror-promql, much of it built by Augustin Hudson, some by myself).

From the official CodeMirror documentation:

For those that don't know the author, Marijn Haverbeke, is the creator of CodeMirror (code editor) and later ProseMirror (text editor).

Performance is mostly handled by CodeMirror (https://codemirror.net/), the underlying editor that Heynote is built upon. It seems to handle quite large buffers well. Where I have seen some minor performance issues is when working with very large blocks in certain language modes.

I don’t think the arrows are possible with VScode?

Someone said they might be possible with CodeMirror https://codemirror.net/

(Just in general - not specifically for racket- I’d love to see this for rust and elixir)

I don't see them on the list of sponsors for the CodeMirror project, but I hope they dedicate some funds for it.

Some background: I am building a custom JSF component. The component is basically a text editor and it should have a "Save" -button for saving the content string of the editor. As I am using the CodeMirror library, I need to fetch the content (string) from the editor with javascript and send that to the server. Therefore, in this case I cannot use XML-based JS invocation such as f:ajax.
