md-link.js

javascript:(function () {
	var selection = window.getSelection().toString();
	var anchor = selection ? selection : document.title;
	void(prompt('', '[' + anchor + '](' + location.href + ')'));
})();

And you say you can't write javascript!

I can write anything. It compiling, making sense and/or doing something is another matter entirely. :)
