title: show org-mode outline up to a certain heading level
body: <p>I'm making an outline for my thesis using org-mode, and I'd like to show all headings up to a certain level (e.g. all level-1 and level-2 headings). </p>
  
  <p>I haven't found anything about that in the org-mode manual. Cycling shows either only level-1 headings, or all headings, which is too much information in my outline right now.</p>
  
  <p>Thanks,</p>

  <p><strong>Update:</strong> I found a workaround for his: set the variable org-cycle-max-level. This is a global setting, though.</p>
