I also missed the pgup/pgdn/home/end keys at first, but I’ve found that this autohotkey scheme works well for me. I don’t even think about it anymore.
Edit: I also want to point out the final script I’m currently using: PgUp PgDn Home End Keys - #5 by brianshmrian. This configuration supports combos like ctrl+left, ctrl+right, ctrl+home, ctrl+end, etc… which I realized are pretty important in my typical navigation.
