Yes, thanks.  I've more or less worked out by trial and error that the 
cross-staff knees only work in \context PianoStaff.  Trying to do it in 
anything else zaps the whole of the rest of the file!

 angle type brackets attached to the system?

Okay, but GrandStaff won't allow knees across staves.  Is there any way 
to force the angle brackets onto PianoStaff?

I'm not out of the woods yet, as I recollect seeing that PianoStaff will 
not allow hiding empty staves, and in all the 5 pages or so of this 
score there are only three lines of double staff system, so I need to 
find a way to switch back and forth...

Anyway, thanks for the help.  The manuals are very extensive and good, 
but lack the bit in the middle - by which I mean something a bit more 
in depth between the tutorial level of info and the (to non-C-coders) 
inscrutable pages about contexts and classes etc., you know, examples 
of how to move a slur up one unit at the right hand end only, how to 
get a slur to cross voices (I have really tied such knots doing that 
and got only indifferent results!), and so on...
