All of the sheva vowels are marked with an unbolded sheva mark. DavkaWriter has a second sheva mark that is bolder. "Tikkun Kor'im-Simanim" uses a bold sheva to mark sheva na'. This macro uses the following rules to identify and mark each instance of sheva na' with a bold sheva mark. Figure 23 shows the result of running the text from Macro 2 through Macro 3.

• Replace sheva under the first letter of a word with bold sheva na'.
  
  
• Replace sheva under a letter‑with‑a‑dagesh with bold sheva na'.
  
  
• Replace sheva under the first of two identical letters with bold sheva na'.
  
  
• Replace sheva after a long vowel (cholam, cholam‑vav, tsere, tsere‑yod, hirik‑yod) with bold sheva na'. Kamatz‑gadol cannot always be differentiated from kamatz‑katan with these macros. Future work may seek to find a way to do this.
  
  
• Replace second of two shevas in a row with bold sheva na'.
  
  
• Fix Hashem's name - replace bold sheva na' under first letter of tetragrammaton with sheva nach.
