New keyboard and no Numpad

[Adekq]

I have a bit of a problem. I replaced my old keyboard with a new TKL one, which means it doesn't have a Numpad. The issue is that I can't change my mouse sensitivity mid-flight. I know I can do it in the menu, but I often changed it during a jump. Is there a solution for this, or a way to reassign the keys?

Fn + up/down arrow may do the same as PgUp and PgDn keys. Of course it's not that convenient to press multiple keys...

Jussi do you know the key how to move camera freely when having Ctrl + F mode activated so for example to go inside the buildings etc.: I'm wondering how this one YouTuber does that
