[NAME]  No, Fn Lock only pertains to the actual F keys along the top row. So with that system’s keyboard layout, that’s all you’ll get. I believe that a recent BIOS update on that particular system made it possible to activate Home/End by pressing Fn+Left/Right, which is handy because Home, End, and PgUp/Dn are frequently used in quick succession, so in that sense having all of them grouped together is nice even if they’re all “Fn-mapped”. Until recently, Home/End could only be activated on the top row, while PgUp/Dn could only be activated via arrow keys, which triggered literally hundreds of complaints across many threads on this forum because it became annoying to have to move your hand frequently to use those keys back to back. So at least that’s improved, but there isn’t a way to make the actual arrow key function “Fn-mapped” and have the default function of those keys be PgUp/Dn — though that setup seems like it would introduce annoyances all on its own, at a bare minimum a muscle memory problem when switching to any other keyboard that wouldn’t be set up that way. Dell’s Latitude keyboards at least until recently had dedicated PgUp/Dn keys in the blank areas left by the “inverted T” arrangement of the arrow keys (i.e. above the Left and Right keys), I guess as an acknowledgement that they were business systems and those keys were more likely to be used by business users, but even they seemed to have dropped that with newer models. But even when those existed, the end result was that PgUp/PgDn could be activated directly, while Home/End required using Fn, which could become a bit odd as well.
Hello fellow Dell users, Got the new laptop and could not be happier, except I dearly miss being able to page up and down using 1 hand. Having to press the Function with my left is really annoying, since I read off my screen a lot. Before you say anything about the Function lock - I tried it. It does let me use the F1 - 12 buttons without having to press Function key but for some reason the arrow buttons are not affected. Is there any way to achieve what I want on this laptop - e.g. being able to page up and down without having to use Function key? Thank you, everyone!

Fn key. Fn lock does not appear to work for this
