I rather keep things to outline-minor-mode than apply org functionality.  Originally,
Was using org-mode as the major buffer but that removed programming highlighting.

Outline should take care of such things itself rather than workarounds with org
functionality.

But LEVELS defaults to the level of the *current heading* or to 1 if the
*current line is not a heading*.  This means I got to go to a heading.

The problem occurs for long files, because I am forces to navigate the file.
If the heading level is deep, it is difficult to search through.
