About

Terminal Key Inspector: Instantly discover JavaScript keyboard event codes within a highly stylized CRT Terminal interface!

Whether you are a frontend web developer building complex forms or a web game creator handling character movement, dealing with JavaScript keyboard events is a daily task. The Terminal Key Inspector is a lightning-fast, lightweight developer tool that instantly reveals the exact keycodes and event properties of any key you press, directly from your browser toolbar.

Breaking away from standard, rigid developer tools, this extension features a meticulously stylized interface inspired by classic 1980s CRT hacker terminals. Complete with a glowing green phosphor text effect, authentic scanlines, a blinking cursor, and a crisp, high-resolution icon, testing your keyboard inputs has never felt so immersive and visually satisfying!

Key Features:

Real-Time Key Inspection: Simply press any key on your keyboard to instantly reveal its event.key, event.code, and event.keyCode values.

Modifier Key Detection: Automatically detects and highlights if you are holding down any meta keys (Ctrl, Alt, Shift, or Windows/Command) simultaneously.

Stylized Retro UI: A visually stunning, high-contrast terminal design that brings a highly polished, nostalgic hacker aesthetic to your daily coding workflow.

Ultra-Lightweight: Built with clean, optimized code that opens instantly without consuming background memory or slowing down your browser.

Strict Privacy & Security:

100% Offline & Local: This extension operates entirely offline. All keystroke capturing and event parsing are processed locally on your device's memory using built-in browser APIs. It never connects to the internet or external servers.

Zero Data Collection (No Keylogging): We respect your privacy. This tool DOES NOT log, store, or transmit your keystrokes. It only displays the event data temporarily on the screen and clears it the moment you close the popup.

No Permissions Required: Designed for absolute privacy and security, this tool requires absolutely NO intrusive browser permissions to function (it does not request access to your browsing history, storage, active tabs, or web page data).

How to Use:

Pin the Terminal Key Inspector icon to your Chrome toolbar.

Click the icon to open the retro terminal popup.

Press any key (or combination of keys) on your keyboard.

Instantly view the exact JavaScript event data on the screen!
