Fix PageUp/Down Left/Right key functions that were broken by 15.16.0 Update
If you are in the middle of a large spreadsheet, these keys apparently move the cursor off screen, but the display does NOT move. They seem to work OK if you start from the R1C1 cell, but not otherwise. It all worked fine before the 15.16.0 update on 11/10/15.

Thanks for the feedback Anonymous, we have this fixed in the December update.
