The remote has PGUP PGDN keys, said to work in 'Computer mode' when the computer and projector are connected by USB cable.    Useful for Powerpoint and the like.  'The manual does not define computer mode.

 

But PGDN seems to double as the selector of S-VIDEO input.  Any ideas on what 'computer mode' is and how I get PGUP PGDN to work?  Thanks.
