overriding certain default keymaps

[rstha]

You can tweak the precedence of your keymap using Prec which is exported by @codemirror/state to tweak the order of execution of your key bindings. To make sure your binding runs earlier than any other bindings for the same key order you can wrap your binding in Prec.highest

import { Prec } from "@codemirror/state";

Prec.highest(
    keymap.of([
      { key: "Mod-Enter", run: Command }
    ])
  ),

The default key maps can be forund here:
