REMOVE-DEFAULT-HINTS!

remove from the default hints non-locally
Major Section:  SWITCHES-PARAMETERS-AND-MODES

Please see remove-default-hints, which is the same as remove-default-hints! except that the latter is not local to the encapsulate or the book in which it occurs. Probably remove-default-hints 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.
