<ms>
The list of prefixes on the General tab contains the braille prefixes used in translating text styles. The prefixes are as follows:

- Style prefix: the code of the braille prefix that can introduce a style code. If omitted the style prefixes will be specified individually, otherwise all the enhanced style prefixes will be preceded by this code. The style prefix is used to contextualize the style code that follows it differently. In this way a style code can have the same points as another braille code;
- Normal style: is the braille code that indicates the transition from a specific style to a normal style;
- Bold: is the braille code that indicates the passage of text to bold style;
- Italic: is the braille code that indicates the passage of the text to the italic style;
- Underlined: it is the braille code that indicates the passage of the text to the underlined style;
- Strikethrough: is the braille code that indicates the passage of text to the strikethrough style;
- Bold italic: is the braille code that indicates the passage of text to the combined bold and italic style;
- Bold-barrel: is the braille code that indicates the passage of the text to the combined bold and strikethrough style;
- Italics-Emphasised: Braille code indicates the passage of text to the combined italic and underlined style;
- Italic-barrel: is the braille code that indicates the passage of the text to the combined italic and barred style.

With reference to Braille codes for other combined styles (e.g. underlined-barred, boldunderlined, etc.), they have been deliberately omitted because they are not used in word processing. Therefore those texts in which other combinations of styles are used it is advisable to correct them because they are improper styles.

Text styles' means the appearance of a text when applied with bold, italic, underlined or strikethrough characteristics. In order to print the text styles in Braille, it is essential that the Braille table used for the preparation has the style fields appropriately enhanced and, in the Braille Settings, choose one of the two useful options in the "Print styles" box.
There are two ways of printing text styles: the Biblos method and the classic method.

The Biblos method is the complete system for printing in Braille all the styles that a text can assume. In Biblos an innovative style marking has been conceived and used, to print the new characteristics of the text introduced with computer science.
In Biblos mode, the change of text style is indicated by the use of special prefixes. All special prefixes dedicated to styles can be customized by entering the properties of the Braille table used for preparation.
Some style combinations are not considered, or are brought back to more appropriate combinations. In addition to the four individual styles of bold, italic, underlined, and strikethrough, Biblos marks combinations of bold italic, bold-barrel, italic-underlined, and italic-barrel.
The marking of the styles is done before the change of style of the text by a double braille code, consisting of style prefix plus style code. The return of the text to the normal style is marked in the same way.

The classic method can only partially print text styles. Classical marking styles considered valid are italic and bold. The underlined style takes the code bold; the strikethrough style is ignored.
The classical marking uses the following special prefixes: bold, italic, bold italic and style prefix.
Classic style marking takes place in two ways: up to three words with the same style, each word is preceded by the code assigned to it. Over three words with the same style, the first word is preceded by two cells, the style prefix and the code, and the last word is preceded only by the style code.
