Accessibility Keys - Where to find them

Hi All,

The consultants that was hired (by another department) to redesign our Plone website somehow manage to break the access keys for accessibility purposes. I was wondering if anyone can point to the the right direction on where to fix the access keys. I was thinking it would be the page_header but I didn't find it there. I have been searching online to no luck.

Thanks in advance

Forgot to add that we are still in 4.1.6
