The font Command
Table 39-3 summarizes the font command. In the table, font is either a description of font parameters, a logical font name, a system font name, or an X font name. The -displayof option applies to X where you can have windows on different displays that can support different fonts. Note that when you delete a logical font name with font delete, the font is not really deleted if there are widgets that use that font.

| font create ?fontname? ?option value ...? | Defines fontname with the specified parameters. |
