 The type specification of =E2=80=98display-buffer-alist=E2=80=99 goes as:
=C2=A0 :type `(alist :key-type
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 (choice :tag "= Condition"
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2= =A0 =C2=A0 regexp
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2= =A0 =C2=A0 (function :tag "Matcher function"))
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 :value-type ,displa= y-buffer--action-custom-type)

This associates regexps/matcher functions with actions.=C2=A0 How, in such = a
specification, can I splice in a buffer name associated with a key
_without_ assigning that pair to the default of =E2=80=98display-buffer-ali= st=E2=80=99?
Maybe I'm missing some detail of the customization interface.

= =E2=80=8BThe detail I think you're missing is that when you add an &quo= t;:options" entry, that is a selectable option, off by default.=E2=80= =8B

=E2=80=8BThe answer to that is= , display-buffer does not know.
=C2=A0

 Whatever he figures out, it will affect the decision whether to display
the buffer initially.

=E2=80=8BInitially, the buffer is not dis= played. Every time output is added to it, it is displayed, by the filter fu= nction. (According to Juri's later message, this is inefficient.)
