As already said, this is not available in the current manual and one 
problem is that
this would still just tell a small part of the full syntax. Another 
problem is that the
rule I gave really was too simple. For example, you cannot say ^"some 
text" in a .ly file
without having a not in front of it, still you can define a macro
mytext = ^"some text"
and then use it as c \mytext
