Toggle an inhibit-er-soft-table entry non-locally
Please see toggle-inhibit-er-soft, which is the same as
toggle-inhibit-er-soft! except that the latter is not local to
the encapsulate or the book in which it occurs. Probably toggle-inhibit-er-soft is to be preferred unless you have a good reason for
wanting to export the effect of this event outside the enclosing encapsulate or book.
