Page Up and Page Down not working in GUI version of the pager

[Daniel J Sebald]

For the pager in the GUI, the Home/End/arrows keys all work but the Page 
Up and Page Down don't cause a window "back" and "forward", 
respectively.  E.g., try

x = ones(200,5)

Page Up and Page Down work in the CLI version of the pager.  Now, it 
could be that this PAGEUP and PAGEDOWN is non-standard and something 
that the Linux bundlers used, as I don't see these keys listed in the 
'h' help when inside the pager.  (There is every key, but those two.)

I miss those keys when in the GUI, though.  Is there a startup file for 
the pager in which key meanings can be defined?
