Actually, reStructuredText does not include a markup alternative for
"one-line section headings" and there is no plan to indroduce them.

The development version 0.17b.dev in the repository has experimental
support for Markdown sources, where they are part of the format
specification.

Some text editors__ will help you with this task.
I use the "JED programmers editor" with rst mode and Search>List_Routines
presents me with an "Outline" window showing the document structure as well as
functions to go to the next or previous section heading.

You may also consider writing your own function to recognize headings,
something along::

   % Check whether the point is in a line underlining a section title.
   % (underline is equal or longer than previous line and previous line is
   % no adornment line and non-blank).
   % Leave point at bol of underline.
   define is_heading_underline()
   {
      !if (up(1)) % already on first line 
         return 0;
      % Get length of heading
      variable heading_len = get_line_len();
      if (not(re_looking_at(".*[a-zA-Z0-9]")))
          heading_len = 0;
      go_down_1();
      !if (heading_len) % blank line, no heading
         return 0;
      % Compare to length of adornment
      return get_line_len() >= heading_len;
   }  

(This is the S-Lang__ code used in the "jed" editor).
