EMSCRIPTEN_KEYBOARD_ELEMENT

A hint that specifies a value to override the binding element for keyboard inputs for Emscripten builds.

The variable can be set to the following values:

• "#window" - the JavaScript window object (this is the default)
• "#document" - the JavaScript document object
• "#screen" - the JavaScript window.screen object
• "#canvas" - the default WebGL canvas element

Any other string without a leading # sign applies to the element on the page with that ID.

By default SDL will use the JavaScript window object.
