/* F15 — the control that says what the analysis looks for, and the dialog it
   opens.

   It used to be a disclosure under the findings line whose summary read "What to
   look for". The words were right and the affordance was wrong: a line of small
   grey text in a column of small grey text, among the disclaimers, which is the
   one part of the page nobody reads looking for a control. So it is an icon in
   the bar now, beside the Dictionary button — what gets masked, and what gets
   pointed out, offered as the same kind of thing — and the list it used to push
   into the pane is a modal, framed like Help and the dictionary.

   The count stays on the trigger's face. It is the part worth knowing without
   opening anything, and it is what tells a passing reader that the icon is about
   a set of things that can be on or off. */
