The codes are the KPS and KPE which Keep Lines Together. Warren Check http://www.brl.org/formats/rule07.html where Braille Formats says: (7) Placement of lists. It is permissible to divide a list between braille pages if this does not adversely affect the clarity of the text. When a list is divided between braille pages, observe the following. (a) A list without a heading should follow the preceding narrative text if there is space at the bottom of the braille page for three listed items. (b) A list with a heading must be started on a new braille page unless there is space at the bottom of the page for the heading and at least two listed items. a snip from the DBT help files ... Keep Lines Together Code Used: [kps] [kpe] What does it do:? As far as possible, it prevents text running over two pages. Where would it be used? If you were preparing a script for a radio presenter for example, the reader would not wish to find a new page in the middle of a sentence or even paragraph. Note that there is a practical limit here. Nothing can be done about paragraphs which are longer than one braille page. In such circumstances you should review the paragraph and decide where it can be split, ideally without being split in the middle of a sentence. Usage in DBT: [kps]These[l]three small[l]lines[kpe] Produces in Braille: ,^! ?ree small l9es Note: These lines would specifically NOT be split over two pages. Let us explain! The [kps] begins the point at which DBT tries to keep the following text on the same page. The [kpe] code basically ends the process. Note: These codes can be placed anywhere in the text. A line break is forced by each of these two codes.
