warning

Be aware of a evaluation context loss, use EvaluationNotebook for such cases if it is called from an external handler, i.e.

(* evaluation context is ok *)
NotebookStore["key"] = 123;

With[{n = EvaluationNotebook[]},
	(* evaluation context is ok *)
	EventHandler[InputButton[], Function[Null,
		(* evaluation context is lost!!! *)
		
		NotebookStore["key", "Notebook"->n] = 124;
							(* manually restore lost info *)
	]]
]
