Modifying a Braille Prefix

This window allows you to change a braille prefix. In the editing field, type in the sequence of braille dots that make up the prefix. The numbers that can be used are from 0 to 8, corresponding to the relevant braille points. In addition, each prefix can be made up of single or multiple cells. If you want to create a multiple-cell prefix, you use a space to separate the numerical sequences.

A braille prefix can also be cancelled, deleting everything. If you want to have an empty braille cell, use the value 0. If you also use dots 7 and 8, you create an 8-dot braille prefix. In this case, the Braille printer must support and be configured for 8-dot printing.
