I can add an extra tab and put a Synedit in it under program control,
and load it with text. What I can't do is hide the original (index
zero) tab: if I do, the Synedit vanishes:

I'm not trying to hide the tab but still see the page, I'm trying to
hide the entire page+tab+content (index zero) and only leave the
newly-created one (again, page+tab+content). But the last time I did any
of this was around about the time that the old TNotebook etc. was
deprecated, and I'm assuming that the rather convoluted sequence I was
using in those days is no longer appropriate.

It hides everything at [0], but also hides the content of [1].
That's because you should not hide the tabsheet, just make the [1] the
active tabsheet (AKA the selected and visible one) and the user will not
be able to select the [0] that has the tab hidden until you show the
hidden tab.
