What Keycode Info does

Keycode Info is a developer utility that captures and displays the JavaScript keyCode, code, location, and modifier flags generated by any keyboard press. It serves as a quick reference for debugging or designing keyboard-driven interfaces, outputting the raw data needed to map keys correctly. The site, IT Tools, hosts this tool as part of a collection of free developer resources. While the live page could not be fetched, the stored notes confirm its core function of reporting detailed key press metadata to aid UI development. Compared to other keycode checkers, this version is embedded within a broader tool directory, offering a straightforward, no-frills interface focused on data output rather than visual demonstrations or complex configurations. It provides the essential information developers need without extraneous features, making it a practical addition to the IT Tools suite for rapid key identification.
