Hmm, the documentation says that PageUp and PageDown act as Up and Down keys - but instead they bring up some dialog for setting the sound volume of the ringer... Instead, the Up and Down keys of the keyboard seem to work as Up and Down keys.
PageUp and PageDown are mapped to the side volume buttons. If you look at the Treo 650 button layout, you'll see that there's no "up/down" button but instead a five-way navigator. Whether that sends vchrPageUp/vchrPageDown or one of the vchrRocker keys depends on what mode the current form is in.
