I couldn't get it to work in Chrome ("keyCode of undefined" errors). This is similar to something I wrote for Automattic recently.

I was pretty pleased with how I tackled annotations across block level elements. Essentially you find your range's start and end containers, and if they match you can just range.surroundContents on them, but otherwise you surroundContents multiple times, once for the start container to its end, once for the end container, from its start until the end of the range, and then for every block element in the middle. Fun stuff.

Thanks for the feedback! At what point in the process did you get those errors? I tested it almost exclusively in chrome and its worked great for me and the friends I sent it to.

I decided not to allow commenting across line breaks because they way I highlight commented text looked weird across line breaks. However I thought my way of allowing commenting over HTML tags (links and such) was pretty cool. I found all HTML tags with a regex and then started removing them one at a time from the bottom of the page until I could find the selected text. This gives me the starting index in the raw HTML of the selection and then I just step through the selection (skipping html tags) to find the ending index. Probably not the most efficient method but it works well!
