Home, End, Page Up, Page Down Keys in OSX

Shortcut keys for navigation are inconsistent in OSX across applications. Notionally the home and end keys are Fn + Left / Right and Page Up / Page Down are Fn + Up/Down. However, this does not always achieve the same navigational effect, especially for programs ported from Windows.
