Also if you used LilyPondTool you would see that it colors the scheme parts, so you would see where the scheme part end. See attached screenshot.

actually, this confuses me too
if the # puts lilypond into scheme mode, does that mean that the equals-sign in #'merge-differently-headed = ##t is not scheme? if it is, then why not #'merge-differently-headed = #t ?

Everything beginning with a # is a Scheme-language expression.
So this sets the property called 'merge-differently-headed to the value #t 
#t is the expression meaning true in Scheme.


Hi Bertalan Fodor,
Okay...assume i knew the word "true" (means =yes or 1, right?), but ##t got double #, so what does the other # means?
He already told you :-) The first # tells LilyPond that "here comes a Scheme 
expression", the "#t" which follows is the actual Scheme code.
