Hello, @FriendOfFred, and All,
I can confirm that, after assigning shortcuts to the SCI_STUTTEREDPAGEUP and the SCI_STUTTEREDPAGEDOWN Scintilla commands, the "UP movement does not act as expected :-((
I, personally, use a local 7.5.6 version of N++, on a Win XP SP3 old laptop. Unfortunately, we do not dispose of any other “Page” command than the default ones and the “stutter” ones.
I don’t think that this behaviour depends on N++ and probably, the best would be to report this bug to SCIntilla :
https://sourceforge.net/p/scintilla/bugs/
You could also test the SCIntilla based text editor, named SciTE :
https://www.scintilla.org/SciTE.html
However, I don’t know if that text editor can manage shortcuts assignments in order to test the “STUTTER” commands !
Best Regards,
