Scribes used many other methods of correction when checking over their work. Rather than attempting to fit corrections in between lines of text, scribes would sometimes use a pairing system to connect corrections made within the margins to the errors within the text. Early on, a commonly used method for this was to write "hd" or "hs" next to an error in the text, linking it to a correction written in the lower or upper margin. However, Latin scribes became confused by this and eventually began using them incorrectly. Instead, scribes began to use signes-de-renvoi, pairing errors and corrections using symbols.
