Hoverintent-like events using special events pattern so they can be used via bind and live

delayedEnter, delayedLeave, and delayedHover.js

//make available as method

	return fn ? this.bind( "delayedEnter", fn ) : this.trigger( "delayedEnter" );

$.attrFn.delayedEnter = true;



//delayedLeave event
$.event.special.delayedLeave = {
	enabled: true,
	
	setup: function() {

//make available as method
$.fn.delayedLeave = function( fn ) {
	return fn ? this.bind( "delayedLeave", fn ) : this.trigger( "delayedLeave" );
};
$.attrFn.delayedLeave = true;

//proxy similar to jQuery's hover
//if leaveCallback isn't defined, enterCallback will apply to both
$.fn.delayedHover = function( enterCallback, leaveCallback ){
	return this.delayedEnter(enterCallback).delayedLeave( leaveCallback || enterCallback );
};
})(jQuery);

Line 102: Why not just $.attrFn.delayedLeave = true? Similar for line 54.
Line 107: No need for $(this), this is already a jQuery object.

fixed. thanks!
