A simple web application that visualizes JavaScript KeyboardEvent key codes when users press any key. Built with Next.js and TypeScript, it is hosted at keycode.info.
Use cases
- find the JavaScript keycode for a pressed key
- look up KeyboardEvent key and code values
- debug keyboard event handling in web apps
- check event.key vs event.code for a key
- reference table of JavaScript key codes
When to choose
- you need to quickly identify key codes for keyboard event handling
- you want a free browser-based key code lookup tool
- you are building or debugging keyboard shortcuts in JavaScript
When to avoid
- you need key code lookup for non-web platforms like native mobile or desktop apps
- you need programmatic key code mapping rather than an interactive visualizer
