Re: PgUp PgDn
If they've really kept the old 7-row Thinkpad layout then those keys are Page Backwards / Page Forwards (works as Back / Fwd in most browsers) and there are dedicated PgUp / PgDn keys at the top right, next to dedicated Home / End. The Fn modifiers for the Home / End increase / decrease LCD backlight brightness.
