+@code{with-simulated-input}, which evaluates one or more forms while
+simulating a sequence of input events for those forms to read.  The result is
+the same as if a user had evaluated the forms and then manually typed in the
+same input.  This macro is useful for non-interactive testing of normally
+interactive commands and functions, such as @code{completing-read}.")
