Full Code Example

## Description
Like [draw()](https://learnpython.strivemath.com/p5-python-web/reference/controlling-the-environment/draw) and [setup()](https://learnpython.strivemath.com/p5-python-web/reference/controlling-the-environment/setup) functions, this function is a built-in function that we override. That is, it **knows when** to run, but it **doesn't know what** do? That's why in the syntax, we just seem to define it, but not call it later.
So, this function runs **when a key is released (regardless if you were holding it or you just pressed it before that)**.
Built-in variables like [`keyCode`](https://learnpython.strivemath.com/p5-python-web/built-in-variables/keyboard#keycode) and [`key`](https://learnpython.strivemath.com/p5-python-web/built-in-variables/keyboard#key) can be used to know which key was released.
