    Help jumps here and the current book is at the end

Practice navigating with the jump line and the browser back and forward to get your bearings. Then come back here for hints and information on the index.

Most browsers allow you to change font size and color. If your browser supports style sheets, you can edit jdoc.css to customize.

The index is for the books as well as from the labs and standard library scripts.

Book references jump to the page. Use your browser search on the page and back to return to the index.

Lab references are the Lab name.

Script references are the short name. Short names are mapped to filenames with noun PUBLIC_j_. Use the short name to directly access the file. For example:
    load 'strings'   NB. string utilities

Scripts with no short name are listed by file name. For brevity the path and .ijs are not included. Two dots separate short names from file names.

Use Edit|Find in Files to search the book html files, scripts, and labs.
