Definition and Usage

A complete key press has two parts, when the key is pressed down, and when the key is released and the key goes up again.

The keyup event occurs when a button is released. It occurs on the element that currently has focus.

The keyup() method triggers the keyup event, or if the function parameter is set, it specifies what happens when a keyup event occurs.

Note: If set on the document element, the event will occur no matter what element has focus.

Note: Use the .which property to get which button was pressed.
