As does MS Windows at the API level, but these messages are intended for 
end users, not programmers, so it is better to follow how the keys are 
labelled on the majority of modern keyboards than the names used in the 
header files.

Personally, the last time I saw these keys labelled Next and Prior was 
in 1992. Since then, every keyboard I have used has labelled them Page 
Up/Page Down or PgUp/PgDn or some other abbreviation.

But I wouldn't suggest changing this until after the release, as it 
probably affects lots of documentation, even if we keep the old names as 
aliases for backwards compatibility.
