That’s a helpful funcion — thanks!

Exactly. As far as the user cares, the setting has a value, even if it’s global.
If I don’t override ChordName.baseline-skip, and my ChordName has a column, the
baseline still skips a certain/exact/known distance. By trial-and-error, I can
find that the default is likely 3:
%%% SNIPPET BEGINS
\version "2.19.35"
testing = \chordmode {
\override ChordName.stencil = #ly:text-interface::print
\override ChordName.text = \markup \column { first second }
c1
\override ChordName.baseline-skip = #5
c1
\override ChordName.baseline-skip = #3
c1
}
\score {
\new ChordNames \testing
}
%%% SNIPPET ENDS

At that point, I say, "Let the user beware.”
My question is: Is there a way to iterate your property display function (or
similar) through all available properties of a grob, and output as a single
list (alphabetically, if possible) the current/default value [e.g.,
ChordName.baseline-skip appears to be 3 by default, or in any case was at the
time my snippet began compiling]?
Thanks,
Kieren.
