Concrete suggestions for dealing with a keyboard without direct Home, End, PageUp, PageDown keys (Fn activated)

Question

First I apologize if this site is not the right place to ask this question. Please feel free to suggest an alternative stackexchange site that suits better the question.

The situation is the following: A laptop keyboard lacks direct Home, End, PageUp, PageDown keys. These keys can be activated using Fn compositions:

Home=Fn+left arrow
End=Fn+right arrow
PgUp=Fn+up arrow
PgDn=Fn+down arrow

(The same laptop lacks also Numpad keys).

This is very inconvenient since Fn are far from arrow keys, and there are many situations where direct access to home, end, are essential. (for example navigating through text in many text editor use home and end).

I am asking this question to know what are the best practices or options to deal with this situation?

In particular, if one would like to address this situation by Autohotkey, what are the best options from user experiences' point of view.

Arrow keys are also essential in many situations and I hesitate the following replacements:

Home <-> left arrow
End <-> right arrow

So first of all, remember that if someone uses Home/End and friends, then irrelevant of whether the only way they can use these keys is using Fn key, they will be used to it by now. And this is true the other way around as well, if someone doesn't like using Home et al, then they probably won't use it in your app.

What I'm saying is, don't worry, the users will be fine irrelevant of whether they use Fn or not. Also you'll probably confuse them when they use Fn+Left_Arrow and nothing happens, 'cause the code was expecting Left_Arrow (btw, I heavily advice that you not go down the remapping route, there's a reason why no one even brings this up).
