Changing tab key behavior

[ionicbuzz]

I'm trying to change the behavior of the tab key such that, when the tab key is pressed, it inserts a '\t' or 	 at the start of the paragraph. This is how I insert the tab with a custom button in the toolbar. The current implementation from listsPlugin() just indents an entire paragraph.

I'm not exactly sure how to implement this, but I think creating a custom realmPlugin is the way to go. However, I'm a bit confused on the documentation for creating a custom realmPlugin. How do I add my own custom realmPlugin to MDX Editor? I'm assuming it needs a custom Lexical node that needs to be initialized with MDX Editor itself.

For example, if I want a custom Lexical node for highlighting selected text, I have the following code:

import { addComposerChild$, addLexicalNode$, realmPlugin } from "@mdxeditor/editor";
import { HighlightNode } from "./LexicalHighlightPlugin";

export const markdownHighlightPlugin = realmPlugin({
    init(realm) {
        realm.pubIn({
            [addComposerChild$]: () => null,
            [addLexicalNode$]: {
                HighlightNode
            }
        });
    }
});

Note that this is just an example for highlighting selected text. I'm planning to create another custom Lexical node for changing the tab key behavior, but I'm not sure if this is the right approach.
