## What it is
Keymaster is a tiny, dependency-free JavaScript micro-library for defining and dispatching keyboard shortcuts in web applications. It supports modifier keys, special keys, shortcut scopes, and querying current key-press state.

## Use cases
- add keyboard shortcuts to a web app
- bind ctrl+r or cmd+r style hotkeys in JavaScript
- reuse the same shortcut in different scopes of a single page app
- detect which keys are currently pressed for a browser game loop
- implement shift+click style modifier-key interactions

## When to choose
- you need a lightweight, dependency-free hotkey library for the browser
- you want scoped shortcuts in a single page application
- you need to query real-time key state for games or interactions

## When to avoid
- you need shortcuts in a non-browser environment like Node.js
- you want an actively developed library with modern ESM support
- you need rich features like key sequences or per-element binding
