Overview

Instantly capture and display JavaScript keyboard event properties (key, code, keyCode) in a retro terminal UI.

Building a web game or a web app with keyboard shortcuts? Stop console.logging your keystrokes! KeyDetect is an ultra-lightweight, lightning-fast utility designed specifically for front-end developers. Wrapped in a cool, nostalgic Retro Hacker Terminal aesthetic (complete with CRT scanlines and a blinking matrix-green cursor), it allows you to instantly find the exact JavaScript key values of any button on your keyboard. Key Features: Instant Capture: Simply open the extension and press any key to instantly view its exact properties. No setup or console required. Detailed Data Output: Instantly displays the string value of event.key, the physical key location of event.code, and the legacy numeric event.keyCode. Handles Edge Cases: Automatically prevents default browser behaviors (like the Spacebar scrolling the page down or the Tab key shifting focus) so you can safely capture every single key without interruption. Retro Terminal UI: Take a break from modern flat design with a highly stylized, authentic command-line interface look. 100% Offline & Secure: KeyDetect runs entirely on your local machine. It requires zero invasive browser permissions, does not inject scripts into your web pages, and operates completely offline. Save time looking up keycodes on the internet. Keep KeyDetect in your toolbar, press a key, and get back to coding!
