Should this return a status indicating whether it was found?

Not currently needed but probably a good design for this helper function.

   // Return true if it's an event on a menu.
   bool IsMenuEvent(views::View* view, int type);
 
   // Recursively explore all menu items of |menu| and return in |count|
   // the total number of items, and in |index| the 0-based index of
   // |item|, if found. Initialize |count| to zero before calling this
   // method. |index| will be unchanged if the item is not found, so
   // initialize it to -1 to detect this case.
   void RecursiveGetMenuItemIndexAndCount(
       views::View* menu, views::View* item, int* index, int* count);
 
   // Recursively explore the subviews and return the text from the first
   // subview with a role of STATIC_TEXT.
   std::string RecursiveGetStaticText(views::View* view);
 
+  // Return a descendant of this view with a given accessible role, if found.
+  views::View* FindDescendantWithAccessibleRole(

nit: each param on its own line.

Done.
