Hmm - I think I'd be happier calling them "special" characters, because
they *aren't* "globally" reserved - they can always be used freely in
contexts where they aren't keying their special action - for instance::
First we have a #Python literal#, but # this looks like some sort of
- that third '#' is NOT treated specially.

But see above - they (sort of) can.

Ah, well, that *does* make more sense - but I'd still prefer to call
them "special" so you can, erm, unreserve them slightly in future
versions if you wish. And also so they are clearly related in use to
other special characters, like '*'.

It's much the same as the way PEPs work, with '[fred]' keying a
reference to an item "labelled" 'fred' (in some way), but being a Wiki
page, references off-page are meant to be *very* easy to generate, and
the way one does that is by the CapitalLettersInWords convention.
However, sometimes that needs circumventing (for instance, 'Tibs' won't
trigger such an event, so I would need to type '[Tibs]'). It's OK,
honest, it works well.
