Re: How to fix markup horizontal position relative to edge of page

[Benjamin Bruce]

Quick question, in the scores I am working on I already have a \layout block 
with several other settings within it. How can I insert just the line-width, 
indent, and short-indent settings into the already-existent \layout block 
without creating another one? If I try just 

    #{ 
       line-width = #(+ lw ind)
       indent = #ind
       short-indent = #ind
    #}

for my LilyPond code block, it gives me the error "not a note name: line-width".
Thanks for your Scheme expertise :)
