EZ KeyCode is a free Chrome extension developed by fueroberther. It falls under the category of Browsers and specifically belongs to the Add-ons & Tools subcategory. As its name suggests, this extension allows users to easily obtain keycode information for any pressed key.

The main purpose of EZ KeyCode is to provide a simple solution for those who frequently forget the syntax for keypress and keydown events. With its minimalistic design, the extension offers a straightforward and hassle-free experience.

To use EZ KeyCode, simply click on the extension icon and press any key. The extension will then display the corresponding keycode information. It's important to note that while EZ KeyCode covers the most commonly used keys, it may not work for all possible keys available to users.

The extension achieves its functionality through a popup document that contains event listeners on its DOM elements. These listeners listen for "keydown" events and update the text of the elements based on the key pressed.
