Problem with Logitech 810K Bluetooth Keyboard and Quicknav

Hi all. I have a Logitech 810K Bluetooth keyboard and I'm noticing that the following quicknav commands don't work:
Control up-arrow to get to the top of the screen
Control down-arrow to get to the bottom of the screen
Option right-arrow to go to the next page
Option left-arrow to go to the previous page
Has anyone else had this problem? Is there maybe an extra key I need to add to the combination to make it work on this particular keyboard?
Thanks!
