I want to know all the methods that are part of a button or input box.

The reference doesn’t list them all I think.

You can read through the source code here:

> <https://github.com/processing/p5.js/blob/master/src/dom/dom.js>

Or you can go beyond p5.js and use the underlying native Element object, which is documented here:

> **[Element](https://developer.mozilla.org/en-US/docs/Web/API/Element)**
>
> Element is the most general base class from which all element objects (i.e. objects that represent elements) in a Document inherit. It only has methods and properties common to all kinds of elements. More specific classes inherit from Element.
