Segregated external links
Yep, that's exactly what happens.
The thing with the nav bar - Currently skins do not call Linker::makeExternalLink for links in the sidebar (instead the html is built inside SkinTemplate::makeLink and Skin::addToSidebarPlain, so the LinkerMakeExternalLink hook is not called. At the moment you'd probably have to hook into SkinBuildSidebar which can modify the attributes on individual links in the sidebar, or do something kind of hacky, like make an interwiki that points to http://theantiquegique.com and use that to make an "internal" link to that page which is not subject to $wgExternalLinkTarget .
Well, as I said, I'm no coder. Most of this is just another foreign language to me that maybe in time I'll learn enough to make sense of it all. However, I do want to thank you again, your help has been most appreciated. I've managed a workaround that is quite sufficient for my present needs by inserting a navigational aide at the top of each page. This will do until I can afford more time to experiment.
Again, Thank you so much,
