Keyboard Event Viewer

Interactive tool to test and track any keyboard input event.

Javascript Key Event Test Script

Enter characters in the text box below to see the triggered Javascript events and the values returned. Keypress events are tested in JavaScript. All keyup, keydown, and modifier key events are possible inclusions in this test.

KeyboardEvent

Each event in a KeyboardEvent object specifies a specific interaction between the user and a key (or a key in combination with a set of modifier keys) on the keyboard. The event type (keydown, keypress, or keyup) determines what kind of keyboard activity.

Note that KeyboardEvent events don't include context for user interactions with keyboard keys; they reveal what those interactions were at a low level. Use the input method whenever you have to deal with text.

How to determine which key is being pressed on a keyboard

When troubleshooting keyboard issues, you may need to check whether the computer recognizes the keys being pressed on the keyboard.
