Visualize keyboard events
Keycode Info is an interactive developer utility for visualizing keyboard events. When you press any key, the tool instantly captures and displays the JavaScript Event data, including `event.key`, `event.code`, `event.which` (deprecated but still used), and `event.location`. It is invaluable for game developers, UI engineers building keyboard shortcuts, or anyone debugging input handling. It distinguishes between left/right modifier keys (Shift, Ctrl, Alt) and provides the precise code needed to listen for that specific keystroke in your application logic.
