How do I forward-delete in Windows using an Apple Wireless Keyboard?

http://support.apple.com/kb/ht1171 says that forward-delete maps to but that key doesn't exist on an Apple Wireless Keyboard (as far as I can tell). Anyone know how to achieve this, as well as home, page up, and page down functions?

I've tried https://code.google.com/p/uawks/downloads/detail?name=Install UAWKS 2008.09.17.exe and uxsoft.cz/projects/awk, but these don't support forward-delete, home, page up, or page down.

Thanks!
