This. And you need a bunch of packages, of course. I guess these

build-essential, libncurses5-dev, texinfo, liblockfile-dev,
librsvg2-dev, libgif-dev, libtiff-dev, libpng-dev, libjpeg-dev,
libm17n-dev, libotf-dev, libgpm-dev, libdbus-1-dev, autoconf, automake,
autotools-dev, imagemagick, libgtk-3-dev, libwebkitgtk-3.0-dev,
libgirepository1.0-dev

should get you started.

Yes.  I can also scroll with <prior> and <next>, while <up> and <down>
show the real trick. Pretty weird and cool at the same time. :-) Great
job.
