2) Give the new abbreviation list a name and click Save
3) Select this new abbreviation list by clicking Scripture + Abbreviation List + Select External List.
4) When asked if you want to use this list, click Yes.
5) Now edit the list to add your abbreviations by clicking Scripture + Abbreviation List + Edit External List
6) To add "3 Yoh" to the list, scroll down or using the Find function to 64-3 JOHN.
7) Add a new line 64-3 YOH. Be sure to use all caps.
8) Click OK The abbreviation count (lower right hand corner) should increase by 1 for each new line you add
The program is now ready to use the new abbreviation / book name.
