Fbpdf is a framebuffer pdf and djvu viewer. There are three make targets: fbpdf uses mupdf library for rendering pdf, fbpdf2 uses poppler for the same purpose, and fbdjvu uses djvulibre library for rendering djvu files. The following options are available in all three programs:
fbpdf [-r rotation] [-z zoom_x10] [-p page_number] file.pdf
The following table lists the commands available in fbpdf. Most of them accept a numerical prefix. For instance, '^F' tells fbpdf to show the next page while '5^F' tells it to show the fifth next page.
