width of staff lines. This makes stems almost twice as thick as their
normal size. To distinguish between variables defined in input files (like
@code{twentyFour} in the example above) and variables of internal
-objects, we will call the latter ``properties'' and the former
-``identifiers.'' So, the stem object has a @code{thickness} property,
+objects, we will call the latter @q{properties} and the former
+@q{identifiers.} So, the stem object has a @code{thickness} property,
while @code{twentyFour} is an identifier.
