The keyboard I was mentioning isn't a laptop keyboard, actually, but laptop keyboards tend to be in a slightly better spot as the major vendors typically have Fn shortcuts for the missing keys, like Fn+B for Break, and they also document them in the user guides.

Detached keyboards seem to be more of a wild west, especially when they target multiplatform -- and it's always the stuff they don't document that screws you.
