Fetch Me My Rifle

It's been a long weekend. I am now trying to complete my Welsh Bacc (that's right complete). But I am coming across some problems. I have just one question, who formatted these booklets. I want to hunt them down and highlight their face. At random points across the documents, certain sections are highlighted, italic, bold, smaller, a different font, centre aligned, or all of the above. How do you format empty writing sections accidentally? So I have concluded, that due to the fact you would have to be missing you brain to do it accidentally, it must have been done on purpose. So fetch me my rifle, it's time to go hunting.
