/TERMINATE
       /NOTERMINATE

    Determines whether the current equivalence string is to be
    terminated (that is, processed as command input) when you press
    the defined key. The default is /NOTERMINATE, which allows
    you to enter additional input before the equivalence string is
    processed. Pressing the RETURN key after pressing the defined key
    has the same effect as using /TERMINATE in the key definition.
