For most publishing styles, Citation uses italics as the print attribute for

If you prefer to use underscores, you can easily change this.
To set the Preferences for underscores rather than italics:
- Click File, Preferences. The Preferences dialog will display.
- Click the option to use Underscores:

- Click OK to save the change to the Preferences for your datafile.
