+\begin{docTcbKey}[][doc new=2015-01-14]{titlerule style}{=\meta{\texttt{\upshape tikz} keys}}{style, no default}
+  The \meta{\texttt{\upshape tikz} keys} are used to draw a title rule,
+  i.e.\ a rule below the optional title. The width of the rule is controlled
+  by \refKey{/tcb/titlerule}. It may be set directly to a smaller width
+  to create mixed effects with the standard rule.
+  This option is implemented as an \refKey{/tcb/underlay}. Thus, it is not
+  available for \refSkin{standard} and \refSkin{standard jigsaw}, but for
+  all other skins, e.g.\ \refSkin{enhanced}.
+  As an underlay, this option can be used multiple times and is removed
+  by \refKey{/tcb/no underlay}.
