The package puts running, customizable thumb marks in the outer margin, moving downward as the chapter number (or whatever shall be marked by the thumb marks) increases. Additionally an overview page/table of thumb marks can be added automatically, which gives the names of the thumbed objects, the page where the object/thumb mark first appears, and the thumb mark itself at its correct position. The thumb marks are useful for large documents (such as reference guides, anthologies, etc.), where a quick and easy way to find (for example) a chapter is needed.
