NimPro recognizes all six levels of headings in the NIMAS standard.
MegaDots users probably know already that MegaDots supports six levels of headings. In the Document Menu, Heading Setup, you can tell MegaDots what to do with each level of heading.
The situation for DBT is more fluid. At the present time, DBT handles three levels of headings.
You can use the Heading Wizard in the Edit Menu to cut down the number of different levels of headings to the number you want to handle in your braille software.
