A:Answer Hey RickyRicardo! When you download the free Logitech Options software https://www.logitech.com/en-us/software/options.html, you'll be able to edit what the F4 to F12 keys do to your preference. Now, not all every possible function will be listed there obviously, so in your case, the Page Up/Down/Home features can be done by pressing the FN key + one of the arrows (up, down, left, right).
