+      The default predicate is to use any frame other than the selected
+      frame.  If successful, return the window used; otherwise return
+      nil.
+
+      ALIST is an association list of action symbols and values.  See
+      Info node `(elisp) Buffer Display Action Alists' for details of
+      such alists.
+
+      If ALIST has a non-nil `inhibit-switch-frame' entry, avoid
+      raising the frame.  If it has a non-nil `frame-predicate' entry,
+      its value is a function taking one argument (a frame), returning
+      non-nil if the frame is a candidate; this function replaces the
+      default predicate.  If ALIST has a non-nil `inhibit-same-window'
+      entry, avoid using the currently selected window (only useful
+      with a frame-predicate that allows using the selected frame).
+
+      This is an action function for buffer display, see Info
+      node `(elisp) Buffer Display Action Functions'.  It should be
+      called only by `display-buffer' or a function directly or
+      indirectly called by the latter."
