A bookmarklet for linking to fragments inside a text

links.js

javascript:(
	function(win, doc){
		var text = "";
		if (win.getSelection) {
			text = win.getSelection().toString();
		} else if (doc.selection && doc.selection.type != "Control") {
			text = doc.selection.createRange().text;
		}
		url = window.location.toString();
		window.location = url.split("#")[0] + "##" + text;
	}
)(window, document);

Select a fragment of text in a document, click on the bookmarklet, and you'll get a link to that fragment in the address bar in your browser.
