TenKeyLess / 87% refers to keyboards missing the numpad, but otherwise full size. For example, I'm typing this from a Coolmaster Novatouch. The gap between Backspace/Insert and F12/PrintScr might be a little narrower on this particular model? But otherwise it's a standard size keyboard, just missing the numpad. And If anything, the lack of the numpad makes PgUp PgDown even easier to register to, as they're right at the edge.
