+To be more precise, it is not the @code{\clef} command itself that
+prints a clef.  Instead, it sets or changes a property of the
+@code{Clef_engraver}, which then decides by its own whether to
+display a clef or not in the current staff.  The @code{forceClef}
+property overrides this decision locally to re-print a clef once.

+When there is a manual clef change, the glyph of the changed clef
+will be smaller than normal.  This behaviour can be overridden.
