The general idea is that these are for things like \markup and
\appoggiatura (ie stuff that goes inside the music definition), but I
wouldn't object to including things like \version and \score in that index.
Please see:

Ok. i'll see... but I must understand first, document later ;-)
It's really strange for me that the syntax of \score , for example, is never
stated (as far as i found)...

Err... concepts like "block" and "atom" might be familiar to you (as a
programmer), but they're not familiar to me! The simplest way I could
think of writing that part was to talk about "the stuff to the right of..."
Well, I'm still reading and grasping the concepts... I was trying
(still am) to understand how does the parsing (informally) work, which
are the delimiters so to speak; clearly, newlines are not. if I write:
...
xxx = {a b c} \markup "hi"
...
xxx is obviously (obviously?) assigned to {a b c} , the \markup is
independet of it, and could have been in other line.
About the "macro/identifier/variable" concept: I meant: this does not work
%%
xx= \italic
\score { { a^\markup { \xx hi } } }
%%
in spite of this being ok:
%%
\score { { a^\markup{ \italic hi } } }
%%
This shows (i assume) that the assigment of a identifier si not a
static sustitution as (a textual macro, a C #define). I'd like to
understand better what it is... Another example:
%--- this is ok ---
\book {
\score { {a b} \midi{} }
\score { {c d} \layout{} }
}
% -- this is ok, equivalent to previous
scoreA = \score { {a b} \midi{} }
scoreB = \score { {c d} \layout{} }
\book {
\score { \scoreA }
\score { \scoreB }
}
But if one think the identifiers as "having" the text at the right,
one would find a duplication of \score commands; the following would
appear to be the real equivalents of the original:
%--- not valid
scoreA = \score { {a b} \midi{} }
scoreB = \score { {c d} \layout{} }
\book {
\scoreA
\scoreB
}
% -- not valid, neither
scoreA = { {a b} \midi{} }
scoreB = { {c d} \layout{} }
\book {
\score { \scoreA }
\score { \scoreB }
}
hope i'm not being too dense .-) just, it's just i'm trying to
understand better how everything works.
cheers
