You can combine same-type fonts to form a font group. The format of the font group is as follows:
FontGroup.
The group name for the fonts.
The font type. Create font groups for the same type of fonts only (PCF, Type1, TrueType).
The Roman font name in the font group.
The Bold font name in the font group.
The Italic font name in the font group.
The BoldItalic font name in the font group.
For creating a group, only a Roman font entry is required. The Bold, Italic, and BoldItalic fonts are optional. The different types of fonts are used to display the header lines for mail or news articles, for example. If only the Roman font is defined, that font is used in place of other fonts.
