## Description

Monaco Vim Keys brings NeetCode-style editor settings to the Monaco code editors on popular coding practice sites. It attaches the mature monaco-vim keybinding engine to the editor the site already loads — no remote code, no account, nothing leaves your browser.

Features:
<ul><li>Full vim key bindings (default ON): NORMAL/INSERT/VISUAL modes, motions (hjkl, w/b/e, 0/$, gg/G, counts), operators (d, c, y, x, r), undo/redo, o/O/A, / search, and more.</li><li>Relative line numbers (default OFF).</li><li>A subtle floating mode indicator (NORMAL / INSERT / VISUAL) next to the editor.</li><li>Per-site enable toggles plus global Vim / relative-line-number toggles in the toolbar popup. Settings persist and apply instantly — no page reload.</li></ul>
