I've been using mapleread for a few days. I generally like it, though it has a few issues.

But I have an interface question that i can't find documentation for. Maybe someone here knows.

On a book page, at the lower right, is a circle with an arrow. I can't seem to figure out exactly what this does. If anyone can point to documentation I would appreciate it.
thx,
