Element: webkitmouseforcechanged event

Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The non-standard webkitmouseforcechanged event is fired by Safari each time the amount of pressure changes on the trackpad/touchscreen.

webkitmouseforcechanged is a proprietary, WebKit-specific event introduced by Apple to support their Force Touch events feature.

This event first fires after the mousedown event and stops firing before the mouseup event.
