    You can start a heading with any word at all as long as the heading makes sense. Just like with any other sentence ever in any language ever. – RegDwigнt Nov 5 '19 at 10:58

    There was a lot of debate about the content of 'On the origin of species ...' (still ongoing), but I've never heard about anyone getting hot under the collar about that 'on'. – Edwin Ashworth Nov 5 '19 at 12:40
  • @EdwinAshworth At least that one's an actual preposition, unlike with to infinitives. – tchrist Nov 6 '19 at 3:14
  • @tchrist I've legitimised Buzz Lightyear. – Edwin Ashworth Nov 6 '19 at 16:52
