Example

This example demonstrates how to retrieve the state of the SHIFT key. Any key pressed fires the onkeydown event handler, enabling you to retrieve the state of the SHIFT key. Because the onkeyup event handler only fires when a key is released, it always returns false for the SHIFT key's state. The onkeypress event handler only fires when the user presses an alphanumeric key—it will not fire if the SHIFT key is pressed.
