	$('body').on('click', '.clickable', function(e){
		var link = $('a:first', this)
			, href = link.attr('href')
			
		// _blank, command key, ctrl key, middle click
		if (link.attr('target') == '_blank' || e.metaKey || e.ctrlKey || e.which == 2)
			window.open(href, '_blank')
		else
			window.location = href
