Hi Graham,

Would it be helpful to add the following doc snippet to 6.2.3
"Tuplets" in the "Commonly tweaked properties" section? I think it
makes most since immediately after "To avoid printing tuplet numbers,
use ..." and immediately before "Tuplet brackets can be made to run to
prefatory matter or the next note ...".

Use the \tweak function to override nested tuplets beginning at the
same music moment. The special \tweak function is like \override in
that \tweak overrides grob properties. The \tweak function differs
from \override in that \tweak neither specifies a grob name nor
contains an equal sign. Here \tweak specifies fraction text for the
outer TupletNumber and denominator text for the TupletNumber of the
first of the three inner tuplets.

\new Staff {
  \tweak #'text #tuplet-number::calc-fraction-text
  \times 4/3 {
     \tweak #'text #tuplet-number::calc-denominator-text
     \times 2/3 { c'8[ c'8 c'8] }
     \times 2/3 { c'8[ c'8 c'8] }
     \times 2/3 { c'8[ c'8 c'8] }
  }
}

Here \tweak and \override work together to specify TupletBracket
direction. The first \tweak positions the TupletBracket of the outer
tuplet above the staff. The second \tweak positions the TupletBracket
of the first of the three inner tuplets below the staff. Note that
this pair of \tweak functions affects only the outer tuplet and the
first of the three inner tuplets because only those two tuplets begin
at the same music moment. We use \override in the usual way to
position the TupletBrackets of the second and third of the inner
tuplets below the staff.

\new Staff {
  \tweak #'text #tuplet-number::calc-fraction-text
  \tweak #'direction #up
  \times 4/3 {
     \tweak #'direction #down
     \times 2/3 { c'8[ c'8 c'8] }
     \override TupletBracket #'direction = #down
     \times 2/3 { c'8[ c'8 c'8] }
     \times 2/3 { c'8[ c'8 c'8] }
  }
}
