1. To Insert Comments in Googledocs

Simply open up the student's text, place your cursor where you want to insert your comment. Note: do not highlight the text itself because when your student goes to delete your comment, s/he will delete the highlighted text at the same time. This is probably the only thing I don't like about using google docs.

Once your cursor is in place, and making sure no text is highlighted, go to Insert-->Comment.
