if you are not signed in or are a new scratcher, you will be able to see comments, but not add them. it will appear that you added them, but no one else will be able to see them. this is not recommended for school for that reason, but could be used.
if it has ellipses (...), just double click and drag it somewhere. note: if you delete a comment, it will stay in the comment variable. press 0 to delete all comments.
