Spacer rests are available only in note mode and chord mode. In
other situations, for example, when entering lyrics, the
command @code{\skip} is used to skip a musical moment.
-@code{\skip} requires an explicit duration.
+@code{\skip} requires an explicit duration, but this is ignored if
+the lyrics derive their durations from the notes in an associated
+melody through @code{\addlyrics} or @code{\lyricsto}.
