Single letter: 4-3456-23. Begin, end word: 4-3456-2, 4-3456-3. Begin, end phrase: 4-3456-2356, 4-3456-3. Images are replaced by authors' descriptions, and then in an embossed version, a full (numbered) page comes next, which can be manually replaced by a tactile version of the image. A "side-by-side" is a horizontal layout of document elements. The components of a side-by-side are called "panels". Typically panels are images or figures, but can also be items like program listings, tables, or paragraphs. For braille, we let each panel use the full width of the page, so we announce the start, indicating the total number of panels. Then we preface each panel with its number in the sequence. Finally we announce the end because it may be hard to distinguish a final panel from the ensuing text. Items of unordered lists retain their print markers, each followed by a period. The symbols in use are: bullet (dots 456, 256), circle (dots 1246 and a grade one indicator, 123456), and square (dots 456, 1246, 3456, 145). A "side-by-side group" is a sequence down the page of "side-by-side" (see previous note). We announce the start with the number of side-by-side in the group to expect, and let the beginning and ending notes for each side-by-side delineate the sequence. Tabular material is always implemented using a "linear table format". A human transcriber may be able to improve small tables, or larger tables that could use multiple pages when embossed, by using a different format. yes no yes no 4 6 0 1 1 1 1 1 1 0 0 -1 0 newpage cell5 centered centered cell5 cell7 cell5 cell7 cell7 UNDEFINED An exercise group follows.
