If you use the PageUp/PageDown keys to navigate through a PDF
document
with the new Okular, it now slow scrolls. This makes it very difficult
to quickly page through a document to get to where you want (some
datasheets are +500 pages). Normally I would just hold the PageDown and
it would fly through the document, now its about one page per sec which
is hopless
An option to speedup scrolling is holding the ‘Shift’ key while
pressing Page Up/Down.
