Right-clicking anywhere within the theory allows Jane to select \cn{MMT}$\to$\cn{Find\ Views\ to...}$\to$\cn{MitM/smglom} (the main Math-in-the-Middle library), telling her (within less than one second) that 11 Views have been found, the most promising of which points to the theory
\cn{matroid\_theory} (see Figure \ref{fig:use:target}) in the library.

\paragraph{} Using a different library as target, we can for example quickly write down a theory for a commutative binary operator (still using the Math-in-the-Middle foundation), allowing us to search e.g. the PVS Prelude library for any commutative operators, as in Figure \ref{fig:use:pvs}.
