I have a setup where I use the same (PC) keyboard for my PC and my Mac mini using a switch box. I switch back and forth between the two all the time - and in order to stay sane I have re-mapped many of the Mac shortcuts/keys using the Karabiner tool, so they function as they do on my PC (keys like Cut, Paste, Home, End, etc... ).
But I don't seem to be able to find a mapping in Karabiner that makes PgUp and PgDn work the same way on Mac as it does on PC. When I press PgUp / PgDn on Mac it scrolls the page, but don't seem to move the cursor. Funny enough - if I press ALT (Option) + PgUp and ALT + PgDn it does exactly what I want.
So basically, how do I get the PgUp to work as ALT + PgUp and PgDn to work as ALT + PgDn?
