Feature summary:
A pair of buttons, thus:
to skip forwards/backwards three pages in multi-page files (PDF, Djvu, etc.) Activating the button would jump automatically with no further input needed.
Use case(s):
When viewing a multi-page file, Commons displays three pages (current, previous and next) at once. When seeking a particular page, for example an illustration, it is often necessary to use the drop-down page selector to jump forwards (or backwards) three pages at a time.
Benefits:
Quicker navigation, few clicks, easier for keyboard users, all reducing editor fatigue.
[This could make a good student or hackathon task; if not done, a user script might suffice.]
