 Operations similar to those in the \textsf{Selected Hypotheses} and \textsf{Search Hypotheses} views are also available for the cached hypotheses. It is possible to remove, select, and start a proof by contradiction (\icon{rodin/falsify_prover.png}) in the \textsf{Cache Hypotheses} view as well. Interactive proof steps (e.g., rewriting) can also be carried out in the \textsf{Cache Hypotheses} view.

+This view~\ref{fig_ref_01_proving_perspective15} shows the type environment for the current node of the proof (free identifiers and their type). It is accessible through \textsf{Window} $ \rangle $ \textsf{Show View} $ \rangle $ \textsf{Type Environment}.

 \subsubsection{Proof Information View}
 
 This view displays information so that the user can relate a proof obligation to the model. For example, typical information for an event invariant preservation includes the event as well as the invariant in question. For instance, in Figure \ref{fig_ref_01_proving_perspective8}, the hyperlinks \textsf{CreateToken} and \textsf{inv2} can be used to navigate to the containing machine.
