You're right - previously it must have been customized somewhere
outside my own configuration. Ctrl+PageUp/Down works - but I prefer
to have it back the way I had it...

Mmmm... so I guess that there is already an existing key binding
somewhere that does nothing. How do I find the cause for this?

I've tried to get a list using 'xrdb -all -query', but don't find any
keymapping that might interfere.

I don't know what kind of systems can interfere. Xresources, perhaps a
KDE configuration, maybe something Exceed-on-demand - and what else?

It's not really well documented, but check the last lines here:
http://www.nedit.org/help/interface.php#Tabbed_Editing
... which names the action routine next_document(). If I define an menu
item in the action menu which only does this action routine and activate
it by selecting the menu item with the mouse, it works - so although
not well documented, it _does_ work.

I also manage to bind it to alt-F11 (from within the NEdit customize
macro menu) and it works. So the action routine isn't the problem - it
really is the key binding that doesn't work.

(if I remember correctly, the advantage of next_document is that it
cycles through the tabs, also from the last back to the first)

I'm editing the NEdit x-resource file itself, not Xdefaults - so just
quiting and restarting NEdit is enough to re-read the new settings.
