11911	"Option to cancel ""Select"" action"	naoliv	team	"Open a lot of data in JOSM (like http://naoliv.iq.unesp.br/osm/boundaries-brasil.osm.bz2), select some objects with the mouse and then select `-selected`. Now wait forever and regret using `-selected` :-/

Could we have some way to cancel actions like this?
Maybe JOSM could have a dialog saying that the desired action is running, together with a Cancel button."	enhancement	closed	normal	15.10	Core		fixed
