Re: Using several frames on TTYs, switching them, terminology: [Is also: Tabbed buffers]

    Again, why the word "tab"?

Because that's the word they are generally called, in regard to
browsers for instance, and what most computer users will know.

                                The display stratagem seems redundant -
    we've already got frames and windows - so, would it not be a better idea
    to have @def{frame sets}, a collection of frames displayed in the same
    place, any one of which can be selected by its tab?

That's not what a tab should do.  Tabs should operate within a frame.
