Help with "To Coda"

[David Feuer]

I want the place where the music jumps to the coda to be marked with
the words "To Coda" and the coda sign.  If I use
\mark \markup { To Coda \musicglyph #"scripts.coda"}
then the coda mark won't be on the right spot.  Looking through the
documentation, it seems as though \put-adjacent should be able to help
me with this, but I can't for the life of me figure out how to use it.

Thanks in advance,
David Feuer
