I agree that wx treats a wxHtmlWindow as though one could navigate
to it using the keyboard, but I don't know how one can do that.

How? What keystrokes would one use to do this? I must be missing
something.

Am I puzzled just because I'm not using one of those abominable
ms keyboards and therefore don't have an 'application key'? If
special hardware is required to interact with a wxHtmlWindow
through the keyboard, then wouldn't it be better for the library
to detect it?

I'm using the 'skeleton' branch because the 'lmi' branch has no
wxHtmlWindow. That branch's 'mvc_view.xrc' has code like this:

        <object class="sizeritem">
            <flag>wxGROW | wxALIGN_CENTER_VERTICAL | wxALL</flag>
            <object class="wxHtmlWindow" name="controls_htmlwindow">
                <size>400,100</size>
                <style>wxHW_SCROLLBAR_AUTO</style>
                <htmlcode>
                    Controls that manage the same sort of data are
                    interchangeable. This is how the previous tab
                    looks with comboboxes substituted for radioboxes.
                </htmlcode>
            </object>
        </object>

I can't find a way to select that text using only my keyboard.

Perhaps that's just because I'm using wxxrc, and otherwise the
text would be selectable with the keyboard only; but if that is
so, then how can I most cleanly prevent this "dead" window from
receiving focus? Clearly, instead of
  wxWindow* w;
  ...
  if(w && w->IsEnabled() && w->AcceptsFocus())
I could say
  wxHtmlWindow* html_window = dynamic_cast<wxHtmlWindow*>(w);
  if(w && w->IsEnabled() && w->AcceptsFocus() && !html_window)
