Turn the highlighted text into a comment

Thanks. I found that highlighting does create an annotation. The problem was that when I first try, instead of having the selected text as annotation on the left I got just rubbish text. Sorry that I cannot show the screenshoot as I am still considered new in the forum and I am not allowed to upload images.
So my best guess is that my problem is related with the already discussed topic “highlighting text it bleeds into adjoining column”.
