Hi Beverly.
Actually, there is nothing on this page that requires Nemeth. Use the UEB low line (underscore) for the blanks, and contract the word "and".
.- & .- IS .-4
In another setting, regarding the use of the single-word switch indicator in Nemeth context, although its use is limited to only one word at a time, it can be used more than once in a sentence as long as there is Nemeth between them.
