+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.
