Hi! Welcome!

Erm... I'm not sure that this is actually really a junior job. This bug has 
been reported about a year ago, and if it were something relatively simple, 
then I guess the KWord maintainer (who is on holiday now) would have fixed it 
a long time ago. It's such a basic thing to support...

No, it's not a script. The texttool implements the cursor movement. But since 
the text shape knows nothing about the page or the visible area of the text, 
it's quite hard to figure out how to scroll a viewport-sized amount of lines.

I haven't got a clear answer for you, I'd need to dig in this code myself as 
well, I'm afraid. If you want to do something easier in the meantime, there 
are some other issues -- only bugs.kde.org is down right now so it's hard to 
figure something out!
