`bubbles` Read only	Boolean	Whether the event normally bubbles or not
`cancelable` Read only	`Boolean`	Whether the event is cancellable or not
`view` Read only	`WindowProxy`	`document.defaultView` (`window` of the document)
`detail` Read only	`long` (`float`)	A count of consecutive clicks that happened in a short amount of time, incremented by one.
`currentTarget` Read only	`EventTarget`	The node that had the event listener attached.
`relatedTarget` Read only	`EventTarget`	For `mouseover`, `mouseout`, `mouseenter` and `mouseleave` events: the target of the complementary event (the `mouseleave` target in the case of a `mouseenter` event). `null` otherwise.
`screenX` Read only	long	The X coordinate of the mouse pointer in global (screen) coordinates.
`screenY` Read only	long	The Y coordinate of the mouse pointer in global (screen) coordinates.
`clientX` Read only	long	The X coordinate of the mouse pointer in local (DOM content) coordinates.
`clientY` Read only	long	The Y coordinate of the mouse pointer in local (DOM content) coordinates.
`button` Read only	unsigned short	The button number that was pressed when the mouse event was fired: Left button=0, middle button=1 (if present), right button=2. For mice configured for left handed use in which the button actions are reversed the values are instead read from right to left.
