+`facet` A facet that displays the frequency with which a set
+ of terms occur within a specific field. The specific
+ field whose contents are analysed must be specified
+ by the widget's `facet` configuration item, which
+ may conveniently be done by means of the
+ `data-mkws-facet` attribute on the HTML
+ element. The supported facets are "subject",
+ "author" and "xtargets" -- the latter a special case
+ which treats the target providing a record as a
+ facet. Most often, `facet` widgets are generated
+ by a `facets` widget, which knows which facets are
+ required, but they can also be placed individually.
+
+`facets` An area that contains a "Facets" heading and several
+ `facet` widgets. The set of facet widgets generated
+ is specified by the `facets` configuration item,
+ which may be set globally or at the level of the
+ widget or the team. The value of this configuration
+ item is an array of zero or more strings, each
+ naming a facet.
+
+`google-image` A specialisation of the `images` widget which
+ defaults to the `Google_Images` target.
+
+`images` A specialisation of the `records` widget which
+ defaults to the `images` template. Unlike the default
+ summary template, this displays an image from the
+ URL specified by the `md-thumburl` field of each
+ record.
+
+`lang` Provides a selection between the supported set of
+ languages (which defaults to English, German and
+ Danish, but can be configured by the `lang`
+ configuration item, whose value is an array of
+ two-letter language codes).
+
+`log` Initially empty, this widget accumulates a log of
+ messages generated by the widget set, similar to
+ those emitted on the JavaScript console.
+
+`lolcat` A specialisation of the `google-image` widget which
+ defaults to the search-term "kitteh" and
+ auto-executes.
+
+`motd-container` An empty container which the `motd` widget, if any,
+ is moved into for initial display. Usually generated
+ as part of the `results` widget.
+
+`motd` May be provided, containing content to appear in the
+ area where records will later appear. It is moved
+ into this area (the `motd-container` widget) and
+ initially displayed; then hidden when the first
+ search is run. It can be used to provide a "message
+ of the day".
+
+`navi` Shows a list of the facets that have been selected,
+ and allows them to be deselected.
+
+`pager` Shows a list of the available pages of results, and
+ allows the user to navigate to a selected page.
+
+`per-page` Provides a dropdown allowing the user to choose how
+ many records should appear on each page. The
+ available set of page-sizes can be set as the
+ `perpage_options` configuration item, whose value is
+ an array of integers. The initial selected value can
+ be set by the `perpage_default` configuration item.
+
+`progress` Shows a progress bar which indicates how many of the
+ targets have responded to the search.
+
+`query` The input area for a query. Usually generated a `search`
+ widget.
-`targets` x
+`ranking` The result-ranking area, consisting of a `sort`
+ widget and a `per-page` widget. These may instead
+ be specified separately if preferred.
+
+`record` A detailed display of a single record, usually
+ appearing when the user clicks on a summary
+ record. This is generated by the `records` widget.
+
+`records` The area in which summary records appear. (Clicking
+ on a summary record make it pop up as a detailed
+ record.)
+
+`reference` A short summary about a subject specified by the
+ `autosearch` configuration item. This is created by
+ drawing a picture and a paragraph of text from
+ Wikipedia. To work correctly, this widget must be
+ used in a library that provides the
+ `wikimedia_wikipedia_single_result` target.
+
+`results` A large compound widget used to provide the most
+ important results-oriented widgets in a pre-packaged
+ framework: `facets`, `ranking`, `pager`, `navi` and
+ `records`.
+
+`search-form` The search form, containing the query area and the
+ button. Usually generated a `search` widget.
+
+`search` The search box, consisting of a form containing a
+ query area and a button.
+
+`sort` Provides a dropdown allowing the user to choose how
+ the displayed records should be sorted. The
+ available set of sort criteria can be set as the
+ `sort_options` configuration item, whose value is
+ an array of two-element arrays. The first item of
+ each sub-array is a pazpar2 sort-expression such as
+ `data:0` and the second is a human-readable label
+ such as `newest`. The initial selected
+ value can be set by the `sort_default` configuration
+ item.
+
+`stat` A summary line stating how many targets remain
+ active, how many records have been found, and how
+ many of them have been retrieved for display. For
+ most purposes, the `progress` widget may be
+ preferable.
+
+`summary` A short record, included in the list shown when a
+ search is run. When clicked, this generally pops up
+ a detailed `record` widget. This widget is generated
+ by the toolkit in response to search results.
+
+`switch` A pair of buttons allowing the user to switch
+ between viewing the search results (the usual case)
+ or the target list.
+
+`targets` A list of all targets in the present library,
+ showing their ID, the number of records they have
+ found for the current search, any diagnostics they
+ have returned, the number of records that have been
+ returned for display, and the connection state.
