## What it is
Mousetrap is a tiny (~2kb gzipped), dependency-free JavaScript library for binding keyboard shortcuts in the browser. It supports single keys, modifier combinations, and Gmail-style key sequences across keypress, keydown, and keyup events.

## Use cases
- add keyboard shortcuts to a web app
- bind ctrl+k style hotkeys in javascript
- implement gmail-like key sequences
- capture keyboard combinations in the browser
- handle special keys like ? and esc in javascript
- support international keyboard layouts for shortcuts

## When to choose
- you need a tiny, framework-agnostic shortcut library with no dependencies
- you want key sequences and combinations with international keyboard support
- you need broad legacy browser compatibility including IE6+

## When to avoid
- you need shortcuts in non-browser environments like Electron menus or OS-level global hotkeys
- you want a library with active ongoing development and modern maintenance
- you need mouse or pointer event handling alongside keyboard events

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, developer-tools
- domain: web-development, frontend, developer-tools
- platform: browser
- tags: keyboard-shortcuts, hotkeys, keybindings, event-handling, zero-dependency, javascript, nodejs
