True; but Cmd+Up and Cmd+Down are slightly more universal across the “Apple ecosystem”, given that iOS-specific keyboards don’t have Fn keys, but do support those shortcuts. :)
Interesting aside: the “Globe” key on an iPad keyboard-folio (the one that opens the IME chooser) has some but not all of the properties of an Fn key. Globe+Left and Globe+Right work as PgUp/PgDn, but Globe+Up and Globe+Down do not work as Home/End. (Or maybe they do, but Home/End just aren’t bound in any app I’ve tested? I don’t want to write+deploy an iOS keysym tester just to find this out...)
