Parameters

`src`	`(EventTarget\|goog.events.Listenable\|null)`
	The node to listen to events on.
`listener`	`(function(?): ?\|{handleEvent: function(?): ?}\|null)`
	Callback method, or an object with a handleEvent function.
`opt_capt`	`boolean=`
	Whether to fire in capture phase (defaults to false).
`opt_scope`	`(Object\|null)=`
	Element in whose scope to call the listener.
`opt_eventHandler`	`(goog.events.EventHandler\|null)=`
	Event handler to add listener to.

Parameters

`src`	`(EventTarget\|goog.events.Listenable\|null)`
	The node to remove listener from.
`listener`	`(function(?): ?\|{handleEvent: function(?): ?}\|null)`
	Callback method, or an object with a handleEvent function.
`opt_capt`	`boolean=`
	Whether to fire in capture phase (defaults to false).
