How do i detect a keypress such as Page-Down ?

Hi,

New user here, I have googled this but found nothing that helps me.

I have a file of data and want to display it to a user from within a "frame/window/screen" that allows the user to pageup/pagedown through the data.

I can do this mostly, but I cannot detect the pressing of the pageup/pagedown keys.

I can get it to go with say "u[Enter]" for up using read input, but I want it to be one keypress of the pageup key.

Can anyone point me at some info on how to do this ?

Using HP-UX, with KSH-88.

Cheers
Greg
