## What it is
Keypress is a small (~9kb), dependency-free JavaScript library for capturing keyboard input in the browser, focused on games. It supports binding to keydown/keyup, treating any key as a modifier, counting combos, and sequence combos.

## Use cases
- capture keyboard input in a browser game
- detect keyboard shortcuts and hotkeys in javascript
- make any key act as a modifier key
- bind callbacks to keydown and keyup events
- handle sequence combos like konami-style key sequences
- implement wasd-style multi-key movement combos

## When to choose
- you need lightweight, dependency-free keyboard capture for a web game or interactive page
- you need unusual combos where non-modifier keys act as modifiers
- you want keyup and keydown handling with legacy browser (ie8) support

## When to avoid
- you need an actively maintained library with modern ES module packaging and recent fixes
- you need OS-level keyboard hooks outside the browser (e.g. global hotkeys in desktop apps)
- you need input beyond the keyboard such as mouse or gamepad handling
