I agree, and don't get me wrong, I think Rockbox is the best thing since sliced bread (better actually), but that information about resetting with the A button is in a footnote buried in section 10.3.3 in a manual that runs up to section 10.4 and is not referenced in the table of contents. The person who got Rockbox yesterday and changed the microscopic default font to Helvetia, but hit Hebrew instead by mistake due to visibility problems and unfamiliarity will have a hard time finding it.
If this information was in 3.1.1 Player controls in the Quick Start section where there is a picture of the controls, it would be more helpful to the newbie.
