to detect when the content of an element has changed. This is different

keyboard. oninput occurs when the content is changed through any user
interface(keyboard, mouse, etc.). For example, at first type few chars, but
then paste some text to the text areas above and below by selecting 'Paste'
command from context menu or by dragging&dropping and see the difference.
